JWST observations of SN 2024abup: First Detection of CO in a broad-lined Type Ic Supernova and Constraints on r-process Nucleosynthesis
Manisha Shrestha, Lindsey A. Kwok, David J. Sand +42
SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 \pm 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a…
Jets from Scratch: Dynamo-Generated Poloidal Magnetic Fields in 3D Collapsar Simulations
Ho-Sang Chan, Ore Gottlieb, Jonatan Jacquemin-Ide +2
The origin of the large-scale poloidal magnetic field required to power relativistic jets in collapsars remains uncertain. While such a field may be inherited during PNS collapse,…
Spinning into the Gap: Direct-Horizon Collapse as the Origin of GW231123 from End-to-End GRMHD Simulations
Ore Gottlieb, Brian D. Metzger, Danat Issa +3
GW231123, the most massive binary black hole (BH) merger observed to date, involves component BHs with masses inside the pair-instability mass gap and unusually high spins. This ch…
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…
Nuclear Neural Networks: Emulating Late Burning Stages in Core Collapse Supernova Progenitors
Aldana Grichener, Mathieu Renzo, Wolfgang E. Kerzendorf +7
One of the main challenges in modeling massive stars to the onset of core collapse is the computational bottleneck of nucleosynthesis during advanced burning stages. The number of…
r-Process Nucleosynthesis and Radioactively Powered Transients from Magnetar Giant Flares
Anirudh Patel, Brian D. Metzger, Jared A. Goldberg +3
We present nucleosynthesis and light-curve predictions for a new site of the rapid neutron capture process (-process) from magnetar giant flares (GFs). Motivated by observations…
She's Got Her Mother's Hair: Unveiling the Origin of Black Hole Magnetic Fields through Stellar to Collapsar Simulations
Ore Gottlieb, Mathieu Renzo, Brian D. Metzger +2
Relativistic jets from a Kerr black hole (BH) following the core collapse of a massive star ("collapsar") is a leading model for gamma-ray bursts (GRBs). However, the two key ingre…
A Model for Eruptive Mass Loss in Massive Stars
Shelley J. Cheng, Jared A. Goldberg, Matteo Cantiello +3
Eruptive mass loss in massive stars is known to occur, but the mechanism(s) are not yet well-understood. One proposed physical explanation appeals to opacity-driven super-Eddington…
The Asteroseismic Imprints of Mass Transfer: A Case Study of a Binary Mass Gainer in the SPB Instability Strip
Tom Wagg, Cole Johnston, Earl P. Bellinger +3
We present new simulations investigating the impact of mass transfer on the asteroseismic signals of slowly pulsating B stars. We use MESA to simulate the evolution of a binary sta…
The Effects of -Process Enrichment in Hydrogen-Rich Supernovae
Anirudh Patel, Jared A. Goldberg, Mathieu Renzo +1
Core-collapse supernovae are candidate sites for the rapid neutron capture process (-process). We explore the effects of enrichment from -process nuclei on the light-curves o…
Modelling time-dependent convective penetration in 1D stellar evolution
Cole Johnston, Mathias Michielsen, Evan H. Anders +7
1D stellar evolution calculations produce uncertain predictions for quantities like the age, core mass, core compactness, and nucleo-synthetic yields; a key source of uncertainty i…
