Pulsations change the structures of massive stars before explosion: interpreting SN 2023ixf and SN 2024ggi
Eva Laplace, Vincent A. Bronner, Fabian R. N. Schneider +1
Massive red supergiants (RSGs) are known to become hydrodynamically unstable before they explode. Still, the vast majority of supernova (SN) models assume RSG progenitors in hydros…
1D stellar mergers: entropy sorting and PyMMAMS
Max Heller, Fabian R. N. Schneider, Jan Henneco +2
Stellar multiple systems are the norm, not the exception, with many systems undergoing interaction phases during their lifetimes. A subset of these interactions can lead to stellar…
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…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Explosions of pulsating red supergiants: a natural pathway for the diversity of Type II-P/L supernovae
V. A. Bronner, E. Laplace, F. R. N. Schneider +1
Red supergiants (RSGs), which are progenitors of hydrogen-rich Type II supernovae (SNe), have been known to pulsate from both observations and theory. The pulsations can be present…
Binarity at LOw Metallicity (BLOeM): Pipeline-Determined Physical Properties of OB Stars
J. M. Bestenlehner, Paul A. Crowther, V. A. Bronner +8
We aim to determine the physical properties of OB stars from the multi-epoch VLT/FLAMES BLOeM spectroscopic survey of the Small Magellanic Cloud. We apply a pipeline designed to an…
