TV Corvi

TV Corvi

A visual band light curve for TV Corvi, adapted from Howell et al. (1996).[1] The main plot shows the decay from a superoutburt in June of 1994, and the inset plot shows an average of the superhumps seen during that decay.

TV Corvi, also known as Tombaugh's Star, is a dwarf nova of the SU Ursae Majoris type in the constellation Corvus that was first discovered by accident as a mysterious 12th magnitude star on a plate by Clyde Tombaugh while looking for remote planets on May 25, 1932, before its identity was confirmed as a dwarf nova by David Levy in 1990.
