Ultraviolet continuum of a sample of Be stars. (1981). Revista Mexicana De Astronomía Y Astrofísica, 6(1), 215-218. https://astronomia.unam.mx/journals/rmxaa/article/view/1981rmxaa...6..215r

Abstract

IUE spectra obtained in the low dispersion mode were used to analyze the energy distributions in the UV of Alpha Draconis, Tau Orionis, 53 Persei, 48 Librae, Pi Aquarii, and 27 Canis Majoris. Absolute fluxes were determined. The effective temperatures and gravity of the model atmospheres which provide the best fit to the spectra of these stars are presented. Alpha Dra and Tau Ori show no discrepancies with regard to the effective temperature and gravity, while the continuum of 53 Per may be variable. 48 Lib fits the log g = 4 or 4.5 and effective temperature 18,000 K model. Pi Aqr and 27 CMa fit models with effective temperature of 30,000 K and log g = 5.
