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…
Magnetic field generation in mergers of massive main-sequence stars
Sebastian T. Ohlmann, Fabian R. N. Schneider, Friedrich K. Roepke +3
Magnetic fields are found in many astrophysical objects, ranging from galaxy clusters to the interstellar medium of galaxies and neutron stars. Strong surface magnetic fields are a…
Theory, Simulations and Observations of Stellar Mergers
Fabian R. N. Schneider
Stellar mergers are responsible for a large variety of astrophysical phenomena. They form blue straggler stars, give rise to spectacular transients, and produce some of the most ma…
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…
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…
Supernovae from stellar mergers and accretors of binary mass transfer: Implications for Type IIP, 1987A-like and interacting supernovae
F. R. N. Schneider, E. Laplace, Ph. Podsiadlowski
As most massive stars are born in binary and other multiple-star systems, many are expected to exchange mass with a companion star or merge with it during their lives. This means t…
Asteroseismic predictions for a massive main-sequence merger product
J. Henneco, F. R. N. Schneider, M. Heller +2
The products of stellar mergers between two massive main-sequence (MS) stars appear as seemingly normal MS stars after a phase of thermal relaxation, if not for certain peculiariti…
The landscape of binary core-collapse supernova progenitors and the late emergence of Wolf-Rayet winds
Avishai Gilkis, Eva Laplace, Iair Arcavi +2
The majority of core-collapse supernova (CCSN) progenitors are massive stars in multiple systems, and their evolution and final fate are affected by interactions with their compani…
Stellar mergers and common-envelope evolution
Fabian R. N. Schneider, Mike Y. M. Lau, Friedrich K. Roepke
Stellar mergers and common-envelope evolution are fast (dynamical-timescale) interactions in binary stars that drastically alter their evolution. They are key to understanding a pl…
It's written in the massive stars: The role of stellar physics in the formation of black holes
E. Laplace, F. R. N. Schneider, Ph. Podsiadlowski
In the age of gravitational-wave (GW) sources and newly discovered local black holes (BH) and neutron stars (NS), understanding the fate of stars is a key question. Not every massi…
Merger seismology: distinguishing massive merger products from genuine single stars using asteroseismology
Jan Henneco, Fabian R. N. Schneider, Saskia Hekker +1
Products of stellar mergers are predicted to be common in stellar populations and can potentially explain stars with peculiar properties. When the merger occurs after the initially…
Pre-supernova evolution and final fate of stellar mergers and accretors of binary mass transfer
F. R. N. Schneider, Ph. Podsiadlowski, E. Laplace
The majority of massive stars are expected to exchange mass or merge with a companion during their lives. This immediately implies that most supernovae (SNe) are from such post-mas…
Contact tracing of binary stars: Pathways to stellar mergers
Jan Henneco, Fabian R. N. Schneider, Eva Laplace
Stellar mergers lead to diverse phenomena: rejuvenated blue stragglers, magnetised and peculiar stars, transients and nebulae. Using a grid of about 6000 detailed 1D binary evoluti…
Going from 3D to 1D: A one-dimensional approach to common-envelope evolution
V. A. Bronner, F. R. N. Schneider, Ph. Podsiadlowski +1
The common-envelope (CE) phase is a crucial stage in binary star evolution because the orbital separation can shrink drastically while ejecting the envelope of a giant star. Three-…
Convective-core overshooting and the final fate of massive stars
D. Temaj, F. R. N. Schneider, E. Laplace +2
Massive stars can explode in powerful supernovae (SNe) forming neutron stars but they may also collapse directly into black holes (BHs). Understanding and predicting their final fa…
Evolution and final fate of massive post-common-envelope binaries
Dandan Wei, Fabian R. N. Schneider, Philipp Podsiadlowski +3
Mergers of neutron stars (NSs) and black holes (BHs) are nowadays observed routinely thanks to gravitational-wave (GW) astronomy. In the isolated binary-evolution channel, a common…
Pre-supernova evolution, compact object masses and explosion properties of stripped binary stars
F. R. N. Schneider, Ph. Podsiadlowski, B. Müller
Most massive stars are born in binary or higher-order multiple systems and exchange mass with a companion during their lives. In particular, the progenitors of a large fraction of…
Long-term evolution of a magnetic massive merger product
F. R. N. Schneider, S. T. Ohlmann, Ph. Podsiadlowski +3
About 10% of stars more massive than have strong, large-scale surface magnetic fields and are being discussed as progenitors of highly-magnetic w…
The MiMeS survey of Magnetism in Massive Stars: Magnetic properties of the O-type star population
V. Petit, G. A. Wade, F. R. N. Schneider +5
In this paper, we describe an analysis of the MiMeS Survey of O-type stars to explore the range of dipolar field strengths permitted by the polarisation spectra that do not yield a…
