The Keplerian three-body encounter I. Insights on the origin of the S-stars and the G-objects in the Galactic center
Alessandro A. Trani, Michiko S. Fujii, Mario Spera
Recent spectroscopic analysis has set an upper limit to the age of the S-stars, the ~30 B-type stars in highly eccentric orbits around the supermassive black hole (SMBH) in the Gal…
Merging black hole binaries with the SEVN code
Mario Spera, Michela Mapelli, Nicola Giacobbo +3
Studying the formation and evolution of black hole binaries (BHBs) is essential for the interpretation of current and forthcoming gravitational wave (GW) detections. We investigate…
K2-264: A transiting multi-planet system in the Praesepe open cluster
John H. Livingston, Fei Dai, Teruyuki Hirano +31
Planet host stars with well-constrained ages provide a rare window to the time domain of planet formation and evolution. The NASA K2 mission has enabled the discovery of the vast m…
Forming circumnuclear disks and rings in galactic nuclei: a competition between supermassive black hole and nuclear star cluster
Alessandro A. Trani, Michela Mapelli, Alessandro Ballone
We investigate the formation of circumnuclear gas structures from the tidal disruption of molecular clouds in galactic nuclei, by means of smoothed particle hydrodynamics simulatio…
Implementing Tidal and Gravitational Wave Energy Losses in Few-body Codes: A Fast and Easy Drag Force Model
Johan Samsing, Nathan W. C. Leigh, Alessandro A. Trani
We present a drag force model for evolving chaotic few-body interactions with the inclusion of orbital energy losses, such as tidal dissipation and gravitational wave (GW) emission…
