A schematic view of the history of the accretion disk and the intruding object. The three plots starting from the bottom left are snapshots from the numerical simulation, depicting the system at the ...
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...
Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...
Massive star formation (above 8 M⊙) unfolds within dense molecular clouds, where gravitational collapse and angular-momentum conservation give rise to rotating protostellar discs and bipolar outflows.
Astronomers have mapped the 'disk winds' associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star. The findings may offer ...
Astronomers using the James Webb Space Telescope have uncovered surprising evidence about how enormous “super Jupiter” ...
Chondrules are one of the most primitive elements that can serve as a fundamental clue as to the origin of our Solar system. We investigate a formation scenario of chondrules that involves ...
A model of ultraviolet and optical emission from the tidal disruption event AT 2018hyz is shown in this schematic diagram. As an accretion disk forms quickly after the TDE, it generates x-ray emission ...
