Abstract
Analyses of early Lick Obs. spectra and recent high dispersion Kitt Peak National Obs. spectra indicate that IC Peg is a quadruple system having all four spectra visible under favorable conditions. Preliminary spoctroscopic orbital elements are presented for the AB system, and for Bb. The Bab system has been found to be the previously known 5.97-day spectroscopic system. The total mass is found to be between 2 and 3 solar masses only. Thus the brightest of the four stars Ba (F5 IV) -or possibly all four of the stars- must have an abnormally small mass for its luminosity. This system appears to be similar to several others which have apparent ovoriuminous components. Such systems are of interest in regard to stellar evolution.
