Dynamical binary interactions in the 2040s
Nadejda Blagorodnova, Ondřej Pejcha, Tomek Kamiński +15
Dynamical binary interactions such as common envelope (CE) evolution or stellar mergers are a critical phase in the formation of a wide variety of binary phenomena, ranging from bl…
Post-dynamical inspiral phase of common envelope evolution: Binary orbit evolution and angular momentum transport
Damien Gagnier, Ondřej Pejcha
After the companion dynamically plunges through the primary's envelope, the two cores remain surrounded by a common envelope and the decrease of the orbital period s…
Supernovae in colliding-wind binaries: observational signatures in the first year
Ondřej Pejcha, Diego Calderón, Petr Kurfürst
When a core-collapse supernova explodes in a binary star system, the ejecta might encounter an overdense shell, where the stellar winds of the two stars previously collided. In thi…
The luminous red nova AT 2018bwo in NGC 45 and its binary yellow supergiant progenitor
Nadejda Blagorodnova, Jakub Klencki, Ondrej Pejcha +12
Luminous Red Novae (LRNe) are astrophysical transients associated with the partial ejection of a binary system's common envelope (CE) shortly before its merger. Here we present the…
The Explosion Mechanism of Core-Collapse Supernovae and Its Observational Signatures
Ondřej Pejcha
The death of massive stars is shrouded in many mysteries. One of them is the mechanism that overturns the collapse of the degenerate iron core into an explosion, a process that det…
CzeV - The Czech Variable Star Catalogue
Marek Skarka, Martin Mašek, Luboš Brát +62
We present the first release of the Czech Variable star catalogue that currently contains 1228 stars whose variability was discovered by 60 Czech observers. The catalogue contains…
