Tidal Disruption Events

Talks

Tidal disruption events occur when a star ventures too close to a supermassive black hole and is torn apart by tidal forces, producing a luminous flare as the stellar debris fuels the compact object. Interpreting observations requires connecting the complex hydrodynamics of the disrupted debris to the processes that shape the emerging radiation. In this talk, I will present a suite of...

Tidal Disruption Events

Talks

A tidal disruption event (TDE) occurs when a star is torn apart by the strong tidal pull of a supermassive black hole. The disruption results in the formation of an elongated stream of gas which cools down adiabatically due to the tidal stretching. As the temperature drops, the gas is expected to undergo chemical processes, which release thermal energy into the stream, potentially affecting...

29. General-Relativistic Long-Term Evolution Models of Neutron Star Mergers

Chun-Ming Yip (GSI Helmholtzzentrum für Schwerionenforschung GmbH (GSI))

Talks

The kilonova AT2017gfo has demonstrated that neutron-star mergers indeed are astrophysical sites of the r-process, yet the detailed properties of its various ejecta components remain poorly understood. Numerical simulations of neutron star mergers, including all relevant physics ingredients and encompassing both the dynamical merger phase and the subsequent remnant evolution, are essential for...

55. Radiation Hydrodynamics of Fallback Accretion in Tidal Disruption Events

Shane Davis (University of Virginia)

Tidal Disruption Events

Talks

I will present results from recent research by myself and collaborators to study the disruption and fallback accretion during tidal disruption events. Using the state-of-the-art Athena++ and AthenaK codes, we solve the radiation transfer equation to accurately model the radiation forces, which play a key role in these sources that commonly reach super-Eddington fallback rates. I will...
