Title: Uncovering the faintest cataclysmic variables in the SDSS footprint
Abstract:
Cataclysmic variables are an excellent benchmark population to test,
calibrate, and develop binary population synthesis models. The Sloan Digital
Sky Survey (SDSS) produced the deepest and most homogenous CV sample to date,
highlighting the importance of the faintest systems to confirm and calibrate
models. The spectroscopic completeness of SDSS plummets below i=19.1 however,
and it is exactly in this range that the composition of the Galactic CV
population undergoes a major change. Towards fainter magnitudes the fraction
of low-luminosity systems increase and probably dominate the space density of
CVs. We propose here to extend the depth of the SDSS CV sample by obtaining
GMOS spectra of faint CV candidates in the SDSS footprint, to complement
previous Gemini and GTC observations.
