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…
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…
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…
