Searching for stars ejected from the Galactic Centre in DESI
Sill Verberne, Sergey E. Koposov, Elena Maria Rossi +1
Dynamical interactions between stars and the super massive black hole Sgr A* at the Galactic Centre (GC) may eject stars into the Galactic halo. While recent fast ejections by Sgr…
Dynamics of recaptures, ejections and mergers of stellar mass binaries over multiple encounters with SgrA*
Biancamaria Sersante, Zephyr Penoyre, Elena Maria Rossi
A common origin for a host of stellar phenomena in galactic centres is the tidal encounter between stellar binaries and a massive black hole (MBH), known as the ``Hills mechanism''…
Disruptions of stars and binary systems on chaotic orbits in an axisymmetric Milky Way center
Zephyr Penoyre, Elena Maria Rossi, Nicholas C. Stone
Non-spherical potentials allow a wide range of trajectories, both regular and chaotic, whose periapse distances can vary orbit to orbit. In particular chaotic trajectories can brin…
Double progenitor origin of the S-star cluster
Sill Verberne, Elena Maria Rossi, Sergey E. Koposov +3
The origin of the cluster of S-stars located in the Galactic Centre is tied to the supermassive black hole Sagittarius A*, but exactly how is still debated. In this paper, we inves…
