S301 and friends: Measuring the spin of Sgr A*
T. Piran, P. Amaro-Seoane, B. Aytac +15
The discovery of S301 (GRAVITY Collaboration et al., 2026) with pericenter distance rp= 280rg and eccentricity e=0.9825, opens the prospect of measuring the spin parameter of Sgr A…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…
A Scaling Law for the Orbital Architecture of Planetary Systems Formed by Gravitational Scattering and Collisions
Eiichiro Kokubo, Haruka Hoshino, Yuji Matsumoto +1
In the standard formation models of terrestrial planets in the solar system and close-in super-Earths in non-resonant orbits recently discovered by exoplanet observations, planets…
The unreasonable effectiveness of the approximation
Elisha Modelevsky, Nicholas C. Stone, Re'em Sari
In kinetic theory, the classic approach calculates the rate of particle interactions from local quantities: the number density of particles , the cross-section , and…
Radio emission from tidal disruption events produced by the collision between super-Eddington outflows and the circumnuclear medium
Fangyi, Hu, Adelle Goodwin +4
In this Letter, we simulate the collision between outflows from the tidal disruption of a 1M main sequence star around a M black hole and an initially spheric…
Supermassive black holes stripping a subgiant star down to its helium core: a new type of multi-messenger source for LISA
Aleksandra Olejak, Jakob Stegmann, Selma E. de Mink +3
Some stars orbiting supermassive black holes (SMBH) are expected to undergo a gravitational-wave (GW)-driven inspiral and initiate mass transfer on nearly circular orbits. However,…
