Modeling Relativistic Tidal Disruptions of MESA Stars
Liam M. Wang, Giovanni Maria Tomaselli, Zihan Zhou
Tidal disruption events (TDEs) occur when a star passes so close to a black hole that its self-gravity is overcome by the external tidal field. As the star passes, it initially def…
Is S301 the Captured Companion of the Hypervelocity Star S5-HVS1?
Andrea Caputo, Giovanni Maria Tomaselli
Stellar binary disruptions through the Hills mechanism produce two fossils: a hypervelocity star (HVS), and a star tightly bound to the supermassive black hole. Among known galacti…
Evolution of Binaries Under Stochastic Perturbations
Andrea Caputo, Giovanni Maria Tomaselli, Chris Hamilton
We develop a general Fokker-Planck framework describing the dynamical evolution of Keplerian binaries subjected to stochastic perturbations. The formalism provides an algorithmic w…
Self-acceleration of Hardening Binaries
Giovanni Maria Tomaselli, Thomas F. M. Spieksma
A Keplerian binary immersed in a bath of lighter particles hardens by ejecting them through gravitational slingshots. This process drives, for example, the evolution of supermassiv…
