Ross 548 is a variable white dwarf star of the DAV type. It was found to be variable in 1970 [ [http://adsabs.harvard.edu/abs/1971ApJ...163L..89L High-Frequency Stellar Oscillations. VI. R548, a Periodically Variable White Dwarf] , Barry M. Lasker and James E. Hesser, "Astrophysical Journal" 163 (February 1971), pp. L89–L93.] ; in 1972, it was given the variable star designation ZZ Ceti [ [http://adsabs.harvard.edu/abs/1972IBVS..717....1K 58th Name-List of Variable Stars] , B. V. Kukarkin, P. N. Kholopov, N. P. Kukarkina, N. B. Perova, "Information Bulletin on Variable Stars", #717, September 21, 1972.] , which also refers to the entire class of DAV variable white dwarfs.
