Abstract
The catalogue lists coordinates, apparent magnitudes, orbital
parameters, and stellar parameters of the components and other
characteristc properties of 472 cataclysmic binaries, 71 low-mass
X-ray binaries and 113 related objects with known or suspected
orbital periods together with a comprehensive selection of the
relevant recent literature. In addition, the catalogue contains a
list of references to published finding charts for 635 of the 656
objects, and a cross-reference list of alias object designations.
Literature published before 1 January 2003 has, as far as possible,
been taken into account. All data can be accessed via the dedicated
catalogue webpage at http://www.mpa-garching.mpg.de/RKcat/ and
http://physics.open.ac.uk/RKcat/ and at CDS via anonymous ftp to cdsarc.u-strasbg.fr (30.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/404/301. We will update the
information given on the catalogue webpage regularly, initially every
six months.
Key words: catalogs - stars: novae, cataclysmic variables -
stars: binaries: close
Five and a half years after the publication of the previous (6th)
edition of the Catalogue of Cataclysmic Binaries, Low-Mass X-Ray
Binaries and Related Objects (Ritter & Kolb 1998, hereafter RK98),
the amount of new literature and the number of new objects to be
included have again grown so much that it seems worthwhile to publish
an updated edition. The philosophy and the purpose of this catalogue
(now in its 7th edition) have been outlined in the preface to the 3rd
edition (Ritter 1984, hereafter R84) and will not be repeated
here. Rather we briefly recall some of the developments which,
over the past five and a half years, have had (and still have) a major
impact on this catalogue:
- 1.
- The online and current edition of
A Catalog and Atlas of Cataclysmic Variables by Downes et al. (2001, hereafter referred to as DWSRKD) is now the primary
source of accurate coordinates and finding charts for
cataclysmic variables. The DWSRKD catalogue supersedes earlier
editions by Downes & Shara (1993) and Downes et al. (1997), includes an updated version of A
Reference Catalogue and Atlas of Galactic Novae by Duerbeck
(1987), and is supplemented by orbital period information
by the present authors.
- 2.
- An increasing number of CVs are found
serendipitously from large surveys such as e.g. the Sloan Digital
Sky Survey (see e.g. Szkody et al. 2002), or from The All Sky
Automated Survey at
http://www.astrouw.edu.pl/~gp/asas/asas.html.
- 3.
- As a result of systematic searches for
potential double degenerate Type Ia supernova progenitors (see
e.g. Napiwotzki et al. 2001; Marsh 2000; Morales-Rueda et al.
2002) the number of detached short-period double white dwarf
systems has increased dramatically and is likely to
continue to grow sustantially in the future.
- 4.
- We acknowledge the continuing contributions of amateur
astronomers to the field of cataclysmic variables, in particular
to tracking down the superhump periods of SU UMa stars. Results
of such amateur activities can e.g. be found on the webpages of
the Variable Star Network (VSNET) at
http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/ and of the
Center for Backyard Astrophysics (CBA) at
http://cba.phys.columbia.edu/.
- 5.
- Due to the much increased sensitivity and
spatial resolution achievable with present-day X-ray satellites
such as Chandra or XMM-Newton, as well as with large
ground-based optical telescopes (e.g. the VLT or the Keck telescopes) the number of cataclysmic variables (CVs) and
low-mass X-ray binaries (LMXBs) found in globular clusters and
in external galaxies (M 31, M 51) is also rapidly increasing.
- 6.
- Gänsicke & Kube (2002) are in the process of establishing
CVcat, a data base on CVs that aims at a comprehensive
collection of all available data on CVs, and to make them
electronically available to the community. Thus its aims go way
beyond those of DWSRKD or the present catalogue.
In view of the activities by Gänsicke & Kube (2002) and the fact
that with DWSRKD there is already an online CV catalogue one might ask
whether publishing yet another one is justified.
DWSRKD and this catalogue have existed in parallel in paper form
before going electronic, and are complementary as far as CVs are
concerned. Our catalogue focuses on data related to the objects'
binary nature, while DWSRKD gives data that are useful for
observational programmes. In addition, our catalogue includes LMXBs
and related objects, for which there is no comparable alternative
source (the most recent catalogue for LMXBs is by Liu et al. 2001).
The CVcat project by Gänsicke & Kube (2002), on the other hand,
is still under development, and it remains to be seen whether this
project will render our catalogue superfluous.
Compared with the 6th edition, the number of objects listed has
increased by almost 60%. Accordingly the current version of
this catalogue provides tabulated data and references for 656 objects
(472 cataclysmic binaries, 71 low-mass X-ray binaries and 113
related objects).
No attempt has been made to provide a complete bibliography. Rather,
the aim is to give a selection of the most recent and most relevant
references that should allow the user to navigate through the
literature addressing mainly the binary properties of the objects in
question. References that were already included in RK98 are only
repeated if they are required for cross-reference (see below).
Yet more references can be found in the previous four editions (R84;
Ritter 1987, hereafter R87; R90; and RK98) of the catalogue.
Accordingly, the 7th edition provides:
- the tables for all three object classes (cataclysmic
binaries, low-mass X-ray binaries and related objects) in full;
- for each catalogued object a selection of references to the
literature, published after 30 June 1997 (the deadline of RK98).
Earlier references are only included if they are needed for
cross-reference, or in cases where there have been few or no
new publications of relevance;
- a list of selected references to published finding charts.
Additional references may be found in previous editions;
- the Who's Who? file, a cross-reference list of alias names of
the objects catalogued.
Thus the catalogue is complete and self-contained in the tables
and in giving cross-references to alternative object designations.
Every effort has been made to avoid errors and to keep the lists up to
date. Nevertheless, the authors are well aware of the fact that also
this edition will contain errors and may be incomplete with regard to
the criteria stated in the preface to the 3rd edition (R84). It is
certainly incomplete with respect to the references quoted.
All the tabular material contained in this catalogue is published in
electronic form only. It is available from the dedicated catalogue
webpages at the MPA
http://www.mpa-garching.mpg.de/RKcat/, and the
OU http://physics.open.ac.uk/RKcat/, or in electronic form
at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5)
or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/404/301.
In addition to the electronic version we provide postscript files for
a printable stand alone version at both websites.
For the current version of this catalogue, literature published before
1 January 2003 has, as far as possible, been taken into account.
For the future it is our intention to provide semi-annual updates of
the catalogue on the dedicated catalogue webpages.
The objects listed in this catalogue are subdivided into three main
object classes, i.e. into Cataclysmic Binaries, Low-Mass
X-Ray Binaries and Related Objects. The defining
characteristics of the three object classes used here are the
following:
- Cataclysmic Binaries
- are semi-detached binaries consisting of a white dwarf primary (or
a white dwarf precursor) and a low-mass secondary which is filling
its critical Roche lobe. The secondary is not necessarily unevolved.
It may even be a highly evolved star as for example in the case of
the AM CVn-type stars. A more detailed description of the main
characteristics of these objects may be found in Warner (1995) or
Hellier (2001).
In addition, we list among the cataclysmic binaries also the
supersoft binary X-ray sources, because these too are semi-detached
binaries containing a white dwarf, though one in a state of sustained
nuclear burning. More information about these objects can be found in
Greiner (1996, 2000).
- Low-Mass X-Ray Binaries
- are semi-detached binaries consisting of either a neutron star or
a black hole primary, and a low-mass secondary which is filling its
critical Roche lobe. Observationally they are distinguished from
the luminous, massive X-ray binaries by the following main properties:
in general the spectra of the low-mass X-ray binaries (at maximum light)
are devoid of normal stellar absorption features. The ratio of their
X-ray to optical luminosities is much larger than unity (typically it
ranges from
102 to
104). A more detailed description of
the main characteristics of these objects may be found in the review
articles in Lewin et al. (1995).
- Related Objects
- are detached binaries consisting of either a white dwarf or a white
dwarf precursor primary and of a low-mass secondary. The secondary
may also be a highly evolved star. Further information may be found
e.g. in Ritter (1986), Bond (1989), or de Kool & Ritter (1993).
With one possible exception (HD 49798) we do not list among the
related objects detached binaries containing a neutron star, or,
for the lack of known objects, a black hole. Thus we explicitly
exclude binary radio pulsars from our compilation because these are
documented elsewhere (e.g. in the Princeton pulsar catalogue,
Taylor et al. 1993) which is available online at
http://pulsar.princeton.edu/pulsar/catalog.shtml.
According to the subdivision into these three object classes the catalogue
consists of three major parts, hereafter referred to as catalogue
sections. Each of the three catalogue sections is further subdivided into
a table section, where a few characterizing parameters of the
object are tabulated, and a reference section, where a
selection of references is given. Within each of the table sections, the
objects are listed in order of decreasing orbital period. In the
corresponding reference section, however, the objects are listed in
lexigraphical order.
Limited information about where the values given in the tables are
taken from is provided as follows: at the end of a reference from
which a given quantity, say XYZ
, was taken, this quantity is
given in parenthesis, i.e. as (XYZ)
. The quantities for
which this is done are: the periods (Orb.Per.
,
2. Per.
, 3. Per.
, 4. Per.
), the spectral
types (Spectr1
, Spectr2
), the mass ratio
(M1/M2
), the orbital inclination (Incl
), the masses
(M1
, M2
), and, where appropriate, the radii
(R1
, R2
) and the eccentricity (e
).
The catalogue is supplemented by a list giving references to published
finding charts of the objects. In this separate section, the
objects of all three classes are merged and listed in lexigraphical
order. The full form of abbreviated references used is given at the
end of this section.
Finally, the Who's Who? file contains a cross-referenced list of
alias names of the objects catalogued. In order to keep this list
short, the full list of alternative object names appears only once for
each object and is to be found under the standard name used in this
catalogue. If an object is sought under one of its alternative names,
reference to the standard name is given. Wherever possible the
variable name given in the 4th edition of the General Catalogue
of Variable Stars (Kholopov et al. 1985a, 1985b, 1987), or in
its online version at
http://www.sai.msu.su/groups/cluster/gcvs/gcvs/, or in the
Name Lists of Variable Stars (up to and including the 76th list,
Kazarovets et al. 2001) is used as the standard name
here. This section includes also a list of references to various
catalogue acronyms that appear in this compilation. More complete
information of this kind may be found in The First Dictionary of the
Nomenclature of Celestial Objects by Fernandez et al. (1983),
its supplements Lortet (1986a, 1989b), and Lortet & Spite (1986), in
the Second Reference Dictionary of the Nomenclature of Celestial
Objects by Lortet et al. (1994), or online via the
Centre de données astronomiques de Strasbourg (CDS) at
