The origin of dispersion in the wind mass-loss rate--luminosity relation of massive O stars
Jiri Krticka, Iva Krtickova
Stellar winds of hot stars are accelerated by the radiative force that mainly comes from the line transitions of heavy elements. As a result, the wind mass-loss rate is expected to…
New line-driven wind mass-loss rates for OB stars with metallicities down to
Jiri Krticka, Jiri Kubat, Iva Krtickova
We provide new line-driven wind models for OB stars with metallicities down to . The models were calculated with our global wind code METUJE, which solves the hydrod…
The nature of medium-period variables on the extreme horizontal branch I. X-shooter study of variable stars in the globular cluster Cen
J. Krticka, I. Krtickova, C. Moni Bidin +6
A fraction of the extreme horizontal branch stars of globular clusters exhibit a periodic light variability that has been attributed to rotational modulation caused by surface spot…
Hot subdwarf wind models with accurate abundances II. Helium-dominated merger products CD-46 8926 and CD-51 11879
J. Krticka, I. Krtickova, J. Janik +3
We aim to understand the influence of evolutionary modified surface abundances on the strength of the stellar wind in the helium-dominated subdwarfs CD-46 8926 and CD-51 11879. We…
New mass-loss rates of Magellanic Cloud B supergiants from global wind models
J. Krticka, J. Kubat, I. Krtickova
We provide global models of line-driven winds of B supergiants for metallicities corresponding to the Large and Small Magellanic Clouds. The velocity and density structure of the m…
EPIC 206197016: A very hot white dwarf orbited by a strongly irradiated red dwarf
J. Krticka, A. Kawka, Z. Mikulasek +7
Very precise satellite photometry has revealed a large number of variable stars whose variability is caused either by surface spots or by binarity. Detailed studies of such variabl…
