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…

Probing dense environments around Sgr A* with S-stars dynamics

Giovanni Maria Tomaselli, Andrea Caputo

The orbits of stars around Sgr A*, the Milky Way's supermassive black hole, provide a unique laboratory for testing its environment with unprecedented precision. In this work, we c…

Lyman-alpha radiation pressure: an analytical exploration

Giovanni Maria Tomaselli, Andrea Ferrara

We study radiation pressure due to Lyman alpha line photons, obtaining and exploring analytical expressions for the force-multiplier, , as a function of…
