Stars: White Dwarfs, Quasars: General

Scientific paper

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. Based on observations collected at the European Southern Observatory, Paranal, Chile (ESO Programme 65.H-0008).
