What happens when a star swings too close to a black hole?
Some of the most interesting structures on galactic scales are formed via tidal interactions. Today’s paper arrives at some unexpected conclusions about which types of galaxies are most likely to host such tidal features.
You can’t model RW Aurigae as a single star with a disk of material around it, because there is a second star. And you can’t model it as a regular old binary system either, because there are interactions between the stars and the asymmetric disk. The authors of today’s paper create a comprehensive hydrodynamic model that considers many different observations of RW Aurigae.
The gas cloud G2 is rapidly approaching the galactic center. Can tidal disruption events with stellar remnants help constrain its orbit?
In this paper, the authors use near-IR imaging and spectroscopy to determine if G2, a galactic center source about to approach our galaxy’s supermassive black hole, is a gas cloud or a star.
Do all tidal disruption events produce jets? This paper tests the hypothesis that they do!
