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!
What happens when an asteroid and a white dwarf (WD) meet? The asteroid doesn’t get the better end of the deal — and the WD might end up with a brand new debris disk.
If there was a cosmic play with the universe as its stage and the celestial bodies as its actors, undoubtedly there would be one character more notorious than the rest; a villain feared by all: the infamous Black Hole. They are truly the things of nightmares, and for one little star out there, that nightmare came true.
