On the possibility of interpretation of MgII profiles in hybrid stars.

Jasinski, M.

Semiempirical models of expanding chromospheres have been constructed for five hybrid stars by fitting of the computed Mg II profiles to the observational data. The mass loss rates obtained from these models range from 1.34×10^-9 to 3.14×10^-7M_sun;/year. On the basis of energetic considerations a possible mechanism acceleratin…

Search for the circumstellar envelopes around the late-type binary systems.

Glebocki, R.; Sikorski, J.

For 21 G and K type binary systems of luminosity class II-IV analysis of Mg II emission lines based on the IUE archive data is performed in order to establish the main contributor to the h₃ and k₃ absorption features. Asymmetry of the emission as well as shift of absorption relative to the emission center can be used as an in…
