WD2326+049
Basic Info
    2MASS 23284760+0514540
    RA/DE = 23:28:47.3 +05:14:51
    V = 13.05, B-V = +0.16; r' = 13.195, J = 13.132, K = 12.689; UCAC3a = 12.827, Vucac3 = 12.813
    This WD is supposed to have a debris disk (Koester & Wilken, 2006), based on the presence of "metals" in the spectrum (Ca).
    The disk is likely to be very thin, like Saturn's rings, and its orientation is unknown.

    This star is a well-known variable, of the ZZ Ceti type. The dominant period is ~ 10 minutes, and the amplitude of variation can be large.
    There's an article at Wilipedia about it: http://en.wikipedia.org/wiki/G29-38
