Abstract
Gamma(1) Vel is suggested by IUE observations to be an interacting binary system with nonthermal energy sources and the possibility of two high electron temperature regions, as well as mass outflow from one of the components. A UV continuum is obtained which fits the Kurucz (1979) LTE model atmosphere computations for an effective temperature of 20,000 K and log g of about 3. It is noted that these parameters are typical for a B2 III star, such as the spectrum of Gamma(1) Vel as observed in the photographic region.
