New gravitational-wave data support a bimodal black-hole mass distribution
R. Willcox, F. R. N. Schneider, E. Laplace +7
Detailed stellar evolution and supernova models yield a bimodal black-hole mass distribution with a narrow peak around 10 solar masses from stars within a narrow range of progenito…
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…
Supernova-induced binary-interaction-powered supernovae: a model for SN2022jli
Ryosuke Hirai, Philipp Podsiadlowski, Peter Hoeflich +4
We present 3D hydrodynamical modelling of supernova-induced binary-interaction-powered supernovae; a scenario proposed for the peculiar type Ic supernova SN2022jli. In this scenari…
Going from 3D common-envelope simulations to fast 1D simulations
V. A. Bronner, F. R. N. Schneider, Ph. Podsiadlowski +1
One-dimensional (1D) methods for simulating the common-envelope (CE) phase offer advantages over three-dimensional (3D) simulations regarding their computational speed and feasibil…
