The rise of the black hole X-ray binary AT2019wey observed with TESS
Alyana Jusino, Kishalay De, Andrea Antoni
Black hole X-ray binaries (BHXRBs) have traditionally been discovered by X-ray surveys with cadences of hours to days. However, large optical time-domain surveys now provide novel…
Disappearance of a massive star in the Andromeda Galaxy due to formation of a black hole
Kishalay De, Morgan MacLeod, Jacob E. Jencson +11
When a massive star reaches the end of its lifetime, its core collapses and releases neutrinos that drive a shock into the outer layers (stellar envelope). A sufficiently strong sh…
Numerical simulations of the random angular momentum in convection II: delayed explosions of red supergiants following "failed'' supernovae
Andrea Antoni, Eliot Quataert
When collapse of the iron core in a massive red or yellow supergiant does not lead to an energetic supernova, a significant fraction of the convective hydrogen envelope will fall i…
Numerical Simulations of the Random Angular Momentum in Convection: Implications for Supergiant Collapse to Form Black Holes
Andrea Antoni, Eliot Quataert
During the core collapse of massive stars that do not undergo a canonical energetic explosion, some of the hydrogen envelope of a red supergiant (RSG) progenitor may infall onto th…
The hydrodynamic evolution of binary black holes embedded within the vertically stratified disks of active galactic nuclei
Nicholas Kaaz, Sophie Lund Schrøder, Jeff J. Andrews +2
Stellar-mass black holes can become embedded within the gaseous disks of active galactic nuclei (AGNs). Afterwards, their interactions are mediated by their gaseous surroundings. I…
The Evolution of Binaries in a Gaseous Medium: Three-Dimensional Simulations of Binary Bondi-Hoyle-Lyttleton Accretion
Andrea Antoni, Morgan MacLeod, Enrico Ramirez-Ruiz
Binary stars are common. While only those with small separations may exchange gas with one another, even the widest binaries interact with their gaseous surroundings. Drag forces a…
Bondi-Hoyle-Lyttleton Accretion onto Star Clusters
Nicholas Kaaz, Andrea Antoni, Enrico Ramirez-Ruiz
An isolated star moving supersonically through a uniform gas accretes material from its gravitationally-induced wake. The rate of accretion is set by the accretion radius of the st…
