Radio transients from stellar tidal disruption by massive black holes

, 2011
The tidal disruption of a star by a supermassive black hole provides us with a rare glimpse of these otherwise dormant beasts. It has long been predicted that the disruption will be accompanied by a thermal `flare', powered by the accretion of bound ...

Interaction of an Outflow with Surrounding Gaseous Clouds as the Origin of Late-time Radio Flares in Tidal Disruption Events

The Astrophysical Journal
Close encounter between a star and a supermassive black hole (SMBH) results in the tidal disruption of the star, known as a tidal disruption event (TDE).

SMBH in Galactic Nuclei with Tidal Disruption of Stars

, 2014
Tidal Disruption of stars by super massive central black holes from dense star clusters is modeled by high-accuracy direct $N$-body simulation. The time evolution of the stellar tidal disruption rate, the effect of tidal disruption on the stellar density

Tidal Disruption Flares: The Accretion Disk Phase

, 2011
The evolution of an accretion disk, formed as a consequence of the disruption of a star by a black hole, is followed by solving numerically the hydrodynamic equations.

AT2022sxl: A Candidate Repeating Tidal Disruption Event in Possible Association with Two High-energy Neutrino Events

The Astrophysical Journal
We report a candidate repeating tidal disruption event (TDE), AT2022sxl, found from large-field optical survey data. Two flares with a separation time of ∼7.2 yr between the two optical peaks are observed.

Coalescence of Black Hole-Neutron Star Binaries

Living Reviews in Relativity, 2011
We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-

Tidal Disruption Events from Stripped Stars

The Astrophysical Journal Letters
Observations of tidal disruption events (TDEs) show signs of nitrogen enrichment reminiscent of other astrophysical sources such as active galactic nuclei and star-forming galaxies. Given that TDEs probe the gas from a single star, it is possible to test

The formation efficiency of close-in planets via Lidov-Kozai migration: analytic calculations

, 2016
Lidov-Kozai oscillations of planets in stellar binaries, combined with tidal dissipation, can lead to the formation of hot Jupiters (HJs) or tidal disruption of planets.
