Surrogate models for type II supernovae: Probing low-energy explosions and interaction-free regimes
Zhengyang Zhang, Shuai Zha, Nikhil Sarin +3
To address the computational bottleneck of analyzing type II supernova samples from surveys such as the Legacy Survey of Space and Time, we present two STELLA-based neural-network…
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…
SN 2016iog: A fast declining Type II-L supernova with an ultra-faint tail, persistently interacting with circumstellar material
Z. -H. Peng, S. Benetti, Y. -Z. Cai +26
We present optical photometric and spectroscopic observations of the rapidly declining Type IIL supernova (SN) 2016iog. SN 2016iog reached its peak 14 days after explosion,…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
He-accreting oxygen-neon white dwarfs and accretion-induced collapse events
Zhengyang Zhang, Chengyuan Wu, Amar Aryan +3
It has been widely accepted that mass-accreting white dwarfs (WDs) are the progenitors of Type Ia supernovae or electron-capture supernovae. Previous work has shown that the accret…
Electron-capture Rates in Ne for a Forbidden Transition to the Ground State of F Relevant to Final Evolution of High-density O-Ne-Mg Cores
Toshio Suzuki, Shuai Zha, Shing-Chi Leung +1
Electron capture on Ne is critically important for the final stage of evolution of stars with the initial masses of 8 - 10 . In the present paper, we evaluate ele…
