We present an analysis of spectroscopic and photometric data for cool DQwhite dwarfs based on improved model atmosphere calculations. In particular, werevise the atmospheric parameters of the trigonometric parallax sample ofBergeron et al.(2001), and discuss the astrophysical implications on thetemperature scale and mean mass, as well as the chemical evolution of thesestars. We also analyze 40 new DQ stars discovered in the first data release ofthe Sloan Digital Sky Survey.Comment: 6 pages,3 figures, 14th European Workshop on White Dwarfs, ASP Conference Series, in pres
