G29-38 and asteroseismology of cool DA white dwarfs

After gathering many seasons of data on G 29-38,1 find, amongst a plethora of linear combination modes, an underlying stable set of normal / = 1 g-modes, ripe for asteroseismological plucking. I have also found multiplets in the star's FTs, but with unexplained peculiarities. I also report on observations of three other cool DAVs whose class properties support the G 29-38 results and the results of Clemens (1993, 1994) from the hotter DAVs. I find the cool DAVs are also remarkably similar as a
