Abstract
In the ESO Imaging Survey of a 1.27 square degree field in the direction of the south galactic pole ("patch B" ) 32 point sources were identified as white dwarf candidates in the B-V vs. V-I two-color diagram by the EIS team and published as a candidate catalog. One of these was a previously known quasar. We have obtained low resolution spectra of 30 of the remaining sources. Of these only 6 are DA white dwarfs, one is a DQ white dwarf, one a DC. 11 candidates are quasars with redshifts between 1.4 and 3.3. The remaining sources are stars with narrow Balmer lines, in most cases probably field horizontal branch stars.


Key words: stars: white dwarfs -- quasars: general

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
