Solar evolution models with a central black hole
Earl P. Bellinger, Matt E. Caplan, Taeho Ryu +6
Hawking (1971) proposed that the Sun may harbor a primordial black hole whose accretion supplies some of the solar luminosity. Such an object would have formed within the first 1 s…
Simulating the tidal disruption of stars by stellar-mass black holes using moving-mesh hydrodynamics
Pavan Vynatheya, Taeho Ryu, Ruediger Pakmor +2
In the centers of dense star clusters, close encounters between stars and compact objects are likely to occur. We study tidal disruption events of main-sequence (MS) stars by stell…
In-plane Tidal Disruption of Stars in Disks of Active Galactic Nuclei
Taeho Ryu, Barry McKernan, Saavik Ford +4
Stars embedded in active galactic nucleus (AGN) disks or captured by them may scatter onto the supermassive black hole (SMBH), leading to a tidal disruption event (TDE). Using the…
Close Encounters of Star - Black Hole Binaries with Single Stars
Taeho Ryu, Selma de Mink, Rob Farmer +3
Multi-body dynamical interactions of binaries with other objects are one of the main driving mechanisms for the evolution of star clusters. It is thus important to bring our unders…
Collisions of red giants in galactic nuclei
Taeho Ryu, Pau Amaro Seoane, Andrew M. Taylor +1
In stellar-dense environments, stars can collide with each other. For collisions close to a supermassive black hole (SMBH), the collisional kinetic energy can be so large that the…
Accretion onto a Supermassive Black Hole Binary Before Merger
Mark J. Avara, Julian H. Krolik, Manuela Campanelli +3
While supermassive binary black holes inspiral toward merger they may also experience significant accretion of matter from a surrounding disk. We study the dynamics of this system,…
