Supernova interactions with aspherical circumstellar material I: calculations of light curves, AB magnitudes, spectra, and polarisation
Petr Kurfürst, Georgi Bless, Jakub Fišák +5
We present an upgraded detailed numerical calculations of supernova (SN) interactions with significantly aspherical circumstellar matter (CSM), primarily formed as a disc or bipola…
Progress towards a 3D Monte Carlo radiative transfer code for outflow wind modelling: II. 3-D applications
Jakub Fišák, JiÅà 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…
Low-metallicity massive single stars with rotation. III. Source of ionization and C-IV emission in I Zw 18
Dorottya Szécsi, Frank Tramper, Brankica Kubátová +5
Chemically homogeneously evolving stars have been proposed to account for several exotic phenomena, including gravitational-wave emissions and gamma-ray bursts. Here we study wheth…
New Frontiers in the Study of Magnetic Massive Stars with the Habitable Worlds Observatory
Alexandre David-Uraz, Véronique Petit, Coralie Neiner +10
High-mass stars are notable for several reasons: they are characterized by strong winds, which inject momentum and enriched material into their surroundings, and die spectacularly…
Red giant - jet collisions in galactic nuclei I: 3D hydrodynamical model of a few stellar orbits
Petr Kurfürst, Michal ZajaÄek, Norbert Werner +1
Several models have been proposed to explain missing red giants (RGs) near the Galactic centre. Recently, a scenario has been suggested that predicts, among other processes, a long…
Polarization of light from fast rotating Wolf-Rayet stars: A Monte Carlo simulations compared to analytical formula
Slah Abdellaoui, JiÅà KrtiÄka, 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…
