Wind emission of OB supergiants and the influence of clumping
Michaela Kraus, Jiri Kubat, Jiri Krticka
The influence of the wind to the total continuum of OB supergiants is discussed. For wind velocity distributions with β> 1.0, the wind can have strong influence to the total contin…
The H-alpha stellar and interstellar emission in the open cluster NGC 6910
J. Kubat, D. Korcakova, A. Kawka +3
We verify the nature of emission-line stars in the field of the open cluster NGC 6910. % Spectroscopy in the H-alpha region was obtained. Raw CCD frames of spectra of all stars fai…
Standard model atmospheres for A-type stars and non-LTE effects
Jiri Kubat, Daniela Korcakova
The current status of NLTE model atmosphere calculations of A type stars is reviewed. During the last decade the research has concentrated on solving the restricted NLTE line forma…
Mass-loss and multicomponent flow from central stars of planetary nebulae
Jiri Krticka, Jiri Kubat
We calculate multicomponent radiatively driven stellar wind models suitable for central stars of planetary nebulae. Some of these stellar winds may be adequately modelled using one…
Multicomponent stellar winds of He chemically peculiar stars
Jiri Krticka, Jiri Kubat
We calculate multicomponent stellar wind models with inclusion of a helium component applicable to He-rich and He-poor stars. We show that helium does not decouple from the stellar…
Properties and nature of Be stars. XX. Binary nature and orbital elements of gamma Cas
P. Harmanec, P. Habuda, S. Stefl +8
An analysis of accurate radial velocities (RVs) of the Be star gamma Cas from 295 Reticon spectrograms secured between October 1993 and May 2000 allowed us to prewhiten the RVs for…
