Abstract

(Abstract only) W. J. Luyten discovered dozens of variable stars during his proper motion surveys on Harvard plates in the 1930s. Most have remained unstudied to the present day because they are generally fainter than 12th magnitude and Luyten did not publish identification charts. This paper begins an investigation of Luyten’s variables on Harvard patrol plates and presents types, periods, magnitude ranges, and finding charts for UV Pyx, NSV 4234, and NSV 4286.
