Non-conservative Mass Transfer as a Formation Channel for Gaia Black Hole System
Aleksandra Olejak, Jakub Klencki, Alejandro Vigna-Gomez +6
The detected Gaia systems hosting compact objects challenge standard models of binary star evolution. In particular, if the observed black hole (BH) systems evolved in isolation, t…
Unexpectedly Weak General Relativistic Effects in Strongly Relativistic Tidal Disruption Events
Ho-Sang Chan, Taeho Ryu, Julian Krolik +1
Tidal disruption events (TDEs) occur when stars are destroyed by supermassive black holes and are among the brightest nuclear transients. It has been thought that strong relativist…
Asymmetrical thermonuclear supernovae triggered by the tidal disruption of white dwarfs
Pavan Vynatheya, Luc Dessart, Taeho Ryu +1
In a dense star cluster core, a tidal disruption event (TDE) of a white dwarf (WD) can occur if the WD passes within the tidal radius of an intermediate-mass black hole (IMBH). Ver…
The collision and merger products of stars do not look alike: A magnetohydrodynamics comparison
Pavan Vynatheya, Taeho Ryu, Chen Wang +2
A significant fraction of stars experience close interactions, including collisions resulting from gravitational encounters and mergers within close binary systems. These processes…
Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
AREPO-RSG: Aspherical Circumstellar Material and Winds from Pulsating Dusty Red Supergiants in Global 3D Radiation Hydrodynamic Simulations
Jing-Ze Ma, Stephen Justham, Ruediger Pakmor +3
Recent observations have revealed a surprisingly large fraction of hydrogen-rich supernovae (SNe) interacting with dense confined circumstellar material (CSM), whose origin is heav…
