Anomalously slow phase transitions in self-gravitating systems [PDF]
, 2004 Kinetics of collapse and explosion transitions in microcanonical self-gravitating ensembles is analyzed. A system of point particles interacting via an attractive soft Coulomb potential and confined to a spherical container is considered.

Revealing the Progenitor of SN 2021zby through Analysis of the TESS Shock-cooling Light Curve
The Astrophysical Journal Letters, 2023 We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) SN 2021zby. TESS captured the prominent early shock-cooling peak of SN 2021zby within the first ∼10 days after explosion with a 30 minute cadence.

Inferring the core-collapse supernova explosion mechanism with three-dimensional gravitational-wave simulations [PDF]
, 2017 A detection of a core-collapse supernova signal with an Advanced LIGO and Virgo gravitational-wave detector network will allow us to measure astrophysical parameters of the source.

HIERARCHICAL GRAVITATIONAL FRAGMENTATION. I. COLLAPSING CORES WITHIN COLLAPSING CLOUDS [PDF]
The Astrophysical Journal, 2015 We investigate the Hierarchical Gravitational Fragmentation scenario through numerical simulations of the prestellar stages of the collapse of a marginally gravitationally unstable isothermal sphere immersed in a strongly gravitationally unstable, uniform background medium.

Inferring Core-Collapse Supernova Physics with Gravitational Waves [PDF]
, 2012 Stellar collapse and the subsequent development of a core-collapse supernova explosion emit bursts of gravitational waves (GWs) that might be detected by the advanced generation of laser interferometer gravitational-wave observatories such as Advanced ...

Two paths of cluster evolution: global expansion versus core collapse [PDF]
, 2014 All gravitationally bound clusters expand, due to both gas loss from their most massive members and binary heating. All are eventually disrupted tidally, either by passing molecular clouds or the gravitational potential of their host galaxies.

Relativistic Jets in Core-collapse Supernovae [PDF]
The Astrophysical Journal Letters, 2019 Abstract After decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. One common mechanism is a neutrino-driven outflow, but others have been proposed. Among those, a long-standing idea is that jets play an important role in supernova (SN) explosions. Gamma-ray bursts (GRBs) that accompany “

The Iron Yield of Core-collapse Supernovae
The Astrophysical Journal, 2023 We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their ^56 Ni masses from the luminosity in their radioactive tails ( ${M}_{\mathrm{Ni}}^{\mathrm{tail}}$ ) and/or in their maximum light, and the mean ^56 ...

Homologously collapsing stellar cores [PDF]
The Astrophysical Journal, 1980 We investigate the collapse of nonrotating gas spheres with a polytropic equation of state: n = 3, corresponding to y = 4/3. Such polytropes provide a reasonable approximation to collapsing stellar cores during the early phase before nuclear density is reached. We find a family of exact homologously collapsing configurations.
