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…

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,…

Hypervelocity Stars Trace a Supermassive Black Hole in the Large Magellanic Cloud

Jiwon Jesse Han, Kareem El-Badry, Scott Lucchini +5

Hypervelocity stars (HVSs) are produced by the Hills mechanism when a stellar binary is disrupted by a supermassive black hole (SMBH). The HVS Survey detected 21 unbound B-type mai…

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 t…

On the aspect ratio of Oumuamua: less elongated shape for irregular surface properties

A. Vazan, R. Sari

The large brightness variation in the observed lightcurve of Oumuamua is probably related to its shape, i.e., to the ratio between its longest axis and its shortest axis (aspect ra…
