Accretion onto neutron stars and stellar-mass black holes in binary systems powers some of the most energetic phenomena in the Universe. Matter transferred from a companion star forms a geometrically ...

A team of researchers at the Sorbonne University of Paris reports a new way to emulate black hole and stellar accretion disks. In their paper published in the journal Physical Review Letters, the ...

An international team has constructed the most detailed, highest resolution simulation of a black hole to date. The simulation proves theoretical predictions about the nature of accretion disks—the ...

An international scientific team has revealed for the first time the magnetic field transport processes in the accretion flow of a black hole and the formation of a "MAD"—a magnetically arrested ...

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 ...

Black holes are regions of austere darkness, gobbling up everything — even light — that strays too close. But the environment immediately surrounding a black hole is not so dark. Astronomers often ...

Supermassive black holes may tear apart and devour their disk of surrounding dust and gas at a shocking speed, perhaps explaining the behavior of a mysterious class of rapidly brightening quasar.

A new Northwestern University-led study is changing the way astrophysicists understand the eating habits of supermassive black holes. While previous researchers have hypothesized that black holes eat ...

It is thought that the Moon accreted from the protolunar disk that was assembled after the last giant impact on Earth. Due to its high temperature, the protolunar disk may act as a thermochemical ...

For the first time, the rotation of a disk where planets are born has been directly observed by mapping the emission of dust ...
