Structure of Convective-Reactive Zone in a Supernova Progenitor
M. Mocak, C. Meakin, F. Rizzuti +5
Convective-reactive events are phases of stellar evolution where turbulent mixing and nuclear burning directly compete, since their timescales become similar within convection zone…
3D simulations of a complete convective silicon shell burning phase
V. Varma, R. Hirschi, F. Rizzuti +7
We present 3D hydrodynamic simulations of a complete silicon shell burning phase until fuel exhaustion at the end of the evolution of a 14 core-collapse supernova progenit…
Fast-spinning massive black holes from slowly rotating low-metallicity stars: Implications for GW231123
N. H. Ismail, N. Yusof, R. Hirschi +4
The origin of massive black holes in the early universe remains uncertain and still unexplored. Pop III stars are among the first stellar sources capable of producing such remnants…
The Beauty of k2: Probing Stellar Interiors Using Apsidal Motion. I. The Benchmark Massive Binary HD 152248
Sophie Rosu, Luca Sciarini, Sylvia Ekström +4
Over the last decades, several independent studies have shown the need for large convective boundary mixing (CBM) and convective core sizes in massive stars to reproduce a variety…
Phlegethon: a fully compressible magnetohydrodynamic code for simulations in stellar astrophysics
G. Leidi, A. Holas, K. Vitovsky +12
We present PHLEGETHON, a fully compressible, Eulerian magnetohydrodynamic (MHD) code designed for multidimensional simulations in stellar astrophysics. The code uses a time-explici…
Drawing the line between explosion and collapse in electron-capture supernovae -- I. Impact of conductive flame speeds and ignition conditions on the explosion mechanism
Alexander Holas, Samuel W. Jones, Friedrich K. Roepke +5
Electron-capture supernovae (ECSNe) are commonly thought to result in a collapse to a neutron star. Recent work has shown that a thermonuclear explosion is also a possible outcome.…
