Gravitational interactions of stars with supermassive black hole binaries - II. Hypervelocity stars
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
Supermassive black holes (SMBHs) in galactic nuclei can eject hypervelocity stars (HVSs). Using restricted three-body integrations, we study the properties of stars ejected by circ…
Gravitational interactions of stars with supermassive black hole binaries. I. Tidal disruption events
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
Stars approaching supermassive black holes (SMBHs) in the centers of galaxies can be torn apart by strong tidal forces. We study the physics of tidal disruption by a binary SMBH as…
Stellar binaries incident on supermassive black hole binaries: implications for double tidal disruption events, calcium-rich transients, and hypervelocity stars
Eric R. Coughlin, Siva Darbha, Daniel Kasen +1
We analyze the outcome of the interaction between a stellar binary and a supermassive black hole binary (SMBHB) by performing a large number of gravitational scattering experiments…
