Evolution of wide O star binaries through their LBV stage. Population synthesis with mass-ejection-driven orbital evolution
Xiao-Tian Xu, Philipp Podsiadlowski, Norbert Langer +6
Context. Long-period Wolf-Rayet (WR) star binaries produced by mass transfer are predicted to be abundant, but are observationally rare. This yields constraints on the evolution of…
Asteroseismic rotation rates of hot subdwarf B stars hint at transient accretion from leftover common envelope matter
Facundo D. Moyano, Hongwei Ge, Zhanwen Han +6
Asteroseismology enabled measuring the rotation rate in the deep stellar interiors of stars across several evolutionary phases, advancing the theory of angular momentum transport i…
Formation of black holes from He stars
Gang Long, Bo Wang, Philipp Podsiadlowski +5
Massive He stars are potential candidates of type Ib/c supernova (SN) progenitors. Understanding their final fates remains a key issue in astrophysics. In this work, we investigate…
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…
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…
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…
