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…
Revisiting the Evolutionary Status of Massive Stars at the central parsec of the Milky Way
A. C. Gormaz-Matamala, J. Cuadra, B. Kubátová +2
Massive stars and their winds have a large influence in their environment, e.g, determining the accretion rate on to the Galactic Centre (GC) super-massive black hole Sgr A*. The w…
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…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
Where are the binaries? -- Searching for blue horizontal-branch stars in binary systems in the inner Galactic Halo
R. Culpan, M. Dorsch, I. Pelisoli +14
Blue horizontal-branch (BHB) stars are evolved low-mass objects that have completed their core hydrogen burning main-sequence (MS) stage and have lost significant mass during the r…
