Progress towards a 3D Monte Carlo radiative transfer code for outflow wind modelling
Jakub Fišák, Jiří Kubát, Brankica Kubátová +2
Context: Radiative transfer modelling of expanding stellar envelopes is an important task in their analysis. To account for inhomogeneities and deviations from spherical symmetry,…
Analysis of photometric and spectroscopic variability of red supergiant Betelgeuse
Daniel Jadlovsky, Jiri Krticka, Ernst Paunzen +1
Betelgeuse is a pulsating red supergiant whose brightness is semi periodically variable and in February 2020 reached a historical minimum, the Great Dimming. The aims of this study…
HD 60431, the CP2 star with the shortest rotational period -- Physical parameters and period analysis
Z. Mikulasek, E. Semenko, E. Paunzen +5
CP2 stars show periodic photometric, spectroscopic, and magnetic variations with the rotational period. They are generally slow rotators, with rotational periods exceeding half a d…
Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
X-ray irradiation of the stellar wind in HMXBs with B supergiants: Implications for ULXs
J. Krticka, J. Kubat, I. Krtickova
Wind-fed high-mass X-ray binaries are powered by accretion of the radiatively driven wind on the compact star. Accretion-generated X-rays alter the ionization state of the wind. Be…
Photometric signatures of corotating magnetospheres of hot stars governed by higher-order magnetic multipoles
J. Krticka, Z. Mikulasek, P. Kurfurst +1
The light curves of magnetic, chemically peculiar stars typically show periodic variability due to surface spots that in most cases can be modeled by low-order harmonic expansion.…
