Query: Spectroscopy of the candidate pre-CV LTT 560   We present preliminary results on spectroscopic data of the candidate
pre-cataclysmic variable LTT 560. A fit to the flux-calibrated spectrum reveals
the temperature of the white-dwarf primary to be T_eff = 7000 - 7500 K, and
confirms the result of previous studies on the detection of an M5V secondary
star. The analysis of radial velocity data from spectral features attributed to
the primary and the secondary star shows evidence for low-level accretion.
