Notes.
(a) Positions are
from the Hipparcos Catalogue (Perryman
et al. 1997). (b) Spectral
types are from Thorén
& Feltzing (2000); Thévenin & Idiart (1999);
Manoj
et al. (2006); Torres et al. (2006). (c) Distances
are from the Hipparcos Catalogue (Perryman
et al. 1997) (d) From
López-Santiago et al. (2006).
Marked as T Tau-type in SIMBAD astronomical database. (e) Quadruple
system composed of two spectroscopic binaries, Aa+b and Ba+b, separated
by 0
848
(Prato et al. 2001).
IR excess originates from the Ba+b (K7+M1V binary) component (for which
the coordinates are given) (see Laskar
et al. 2009, and references therein). (f) Binary
system with the secondary (M2.5 pre-main-sequence) star located 7
7
to the southwest of the primary (A0V). IR excess comes from
HD 109573A (also designated HR 4796A or
GQ Lup) with an imaged circumstellar ring (Schneider et al. 2009).
(g) Primary
component HD 141569A, which is possibly still in its
pre-main-sequence stage, has a binary companion consisting of two M
stars at
separation. The double pair could be unbound and merely flying by (Reche et al. 2009). (h) Spectroscopic
binary with high IR excess attributed to long-lived primordial,
circumbinary disk (Uzpen
et al. 2007; Gómez de Castro 2009).
