...In general, light curves are complex, with many having multiple periods. Figure 3 shows the light curve of HL-76 Tauri, the star with the widest range of variation in this group. ZZ Ceti stars have the spectrum of a white dwarf star, a DA type, in which only hydrogen absorption lines are strongly visible, and the surface temperature of the star calculated from the color index is limited to a narrow range of 10,000 K to 13,000 K. ... *Some of the terminology used to refer to "Taurus HL-76" is listed below.
