A Statistical Study of the si IV Resonance Line Parameters in 19 Be Stars

Antoniou, A.; Stathopoulos, D.; Danezis, E. +2 more

Using the GR model, we analyze the ultraviolet Si IV resonance lines in the spectra of 19 Be stars of different spectral subtypes, in order to detect the presence of absorption components and to analyze their characteristics. From this analysis we can calculate the values of a group of physical parameters, such as the apparent rotational and radia…

Studying the UV mg II Resonance Lines in 20 Be Stars

Antoniou, A.; Stathopoulos, D.; Danezis, E. +1 more

Using the GR model, we analyze the UV Mg II resonance lines in the spectra of 20 Be stars of different spectral subtypes, in order to detect the presence of satellite or discrete absorption components. The values of some physical parameters -- rotational, radial and random velocities, as well as the FWHM and the absorbed energy, as a function of t…
