Progress towards a 3D Monte Carlo radiative transfer code for outflow wind modelling: II. 3-D applications
Jakub Fišák, Jiří Kubát, Nicolas Moens +1
The massive hot stars play crucial role in the dynamics of galaxies. These stars influence their surroundings through strong winds which are highly structured processes. The theore…
Polarization of light from fast rotating Wolf-Rayet stars: A Monte Carlo simulations compared to analytical formula
Slah Abdellaoui, Jiří Krtička, Brankica Kubátová +1
Fast-rotating Wolf-Rayet (WR) stars are potential progenitors of long gamma-ray bursts, but observational verification is challenging. Spectral lines from their expanding stellar w…
The Great Dimming of Betelgeuse: the photosphere as revealed by tomography over the past 15 years
Daniel Jadlovský, Thomas Granzer, Michael Weber +6
Betelgeuse, a red supergiant star of semi-regular variability, reached a historical minimum brightness in February 2020, known as the Great Dimming. Even though the brightness has…
Supernova explosions interacting with aspherical circumstellar material: implications for light curves, spectral line profiles, and polarization
P. Kurfürst, O. Pejcha, J. Krtička
Some supernova (SN) explosions show evidence for interaction with pre-existing non-spherically symmetric circumstellar medium (CSM) in their light curves, spectral line profiles, a…
Towards comprehension of the variability of the magnetic chemically peculiar star CU Virginis (HD 124224)
Zdeněk Mikulášek, Jiří Krtička, Andrzej Pigulski +2
The upper main sequence stars CU Virginis is the most enigmatic object among magnetic chemically peculiar (mCP) stars. It is an unusually fast rotator showing strictly periodic lig…
What is New with Landstreet Star HD 37776 (V901 Ori)?
Zdeněk Mikulášek, Jiří Krtička, Matthew E. Shultz +6
HD\,37776 (V901\,Ori, B2\,Vp), also known as Landstreet's Star, is possibly the most remarkable magnetic chemically peculiar (mCP) star known. Zeeman Doppler Imaging revealed this…
Modeling of interactions between supernovae ejecta and aspherical circumstellar environments
Petr Kurfürst, Jiří Krtička
Massive stars are characterized by a significant loss of mass either via spherically symmetric stellar winds or pre-explosion pulses, or by aspherical forms of circumstellar matter…
An overview of the properties of a sample of newly-identified magnetic chemically peculiar stars in the Kepler field
Zdeněk Mikulášek, Ernst Paunzen, Stefan Hümmerich +4
We present a comprehensive overview of the properties of a sample of 41 magnetic chemically peculiar stars that have been recently identified in the Kepler field by our team (Hümme…
Unravelling the baffling mystery of the ultrahot wind phenomenon in white dwarfs
Nicole Reindl, M. Bainbridge, N. Przybilla +6
The presence of ultra-high excitation (UHE) absorption lines (e.g., O VIII) in the optical spectra of several of the hottest white dwarfs poses a decades-long mystery and is someth…
