New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic ...
A close encounter more than 10,000 years ago stirred up spirals in the accretion disk surrounding the black hole at the center of our galaxy. Dr. LU Xing, an associate researcher from the Shanghai ...
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 ...
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 ...
Caption Computer simulation of the disruption of a star by a black hole shows the formation of an eccentric accretion disk of stellar material spiraling into the black hole. This image from a video of ...
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 ...

The boundary between stars and planets increasingly blurred
The boundary between stars and planets appears increasingly indistinct. Objects such as brown dwarfs, neither fully stars nor ...
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 ...
