A new model describes for the first time the evolution of the stream of gas that results when a star gets ripped apart by a black hole, working toward an understanding of how radiation is generated in these events.
A proposed mission would touch down at local dusk in 2045, spend 88 Earth days collecting 11 gigabytes of data, then expire as its maximum operating temperature is exceeded as it sees the Sun rise from Mercury’s surface.
A massive star’s extreme dimming episode may be the result of mass loss that obscures the star, analogous to Betelgeuse’s “Great Dimming,” but this scenario makes finding true failed supernovae even more difficult.
New research shows that the apparent discrepancies in the mass and spin of black holes in X-ray binaries compared to those discovered with gravitational waves is the result of a selection effect.
Detailed measurements of stellar trajectories allowed researchers to trace the motions of stars from 5 million years ago to 2 million years in the future, uncovering 119 past flyby events in the Sco-Cen OB association.
A team has collected previous solar wind measurements at the orbit of asteroid (16) Psyche and used them to predict four possible structures for the object’s magnetosphere, which has the potential to be very complex.
