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…
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…
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…
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…
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…
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…
Binary mass transfer in 3D: Mass Transfer Rate and Morphology
T. Ryu, R. Sari, S. E. de Mink +6
Mass transfer is crucial in binary evolution, yet its theoretical treatment has long relied on analytic models whose key assumptions remain debated. We present a direct and systema…
Supermassive black holes stripping a subgiant star down to its helium core: a new type of multi-messenger source for LISA
Aleksandra Olejak, Jakob Stegmann, Selma E. de Mink +3
Some stars orbiting supermassive black holes (SMBH) are expected to undergo a gravitational-wave (GW)-driven inspiral and initiate mass transfer on nearly circular orbits. However,…
Light curves and spectra for stellar collisions between main-sequence stars in galactic nuclei
Taeho Ryu, Luc Dessart
High-velocity stellar collisions in galactic nuclei produce ejecta that generate potentially observable electromagnetic radiation, making them promising nuclear transients. However…
Blue straggler stars
Chen Wang, Taeho Ryu
Blue straggler stars are unique main-sequence stars that appear more luminous, hotter, and therefore younger, than their coeval counterparts. In star clusters, these stars are loca…
Magnetic Field Amplification during Stellar Collisions between Low-Mass Stars
Taeho Ryu, Alison Sills, Ruediger Pakmor +2
Blue straggler stars in stellar clusters are a subset of stars that are bluer and appear younger than other cluster members, seemingly straggling behind in their evolution. They of…
The look of high-velocity red-giant star collisions
Luc Dessart, Taeho Ryu, Pau Amaro Seoane +1
High-velocity stellar collisions driven by a supermassive black hole (BH) or BH-driven disruptive collisions, in dense, nuclear clusters can rival the energetics of supergiant star…
