Astronomers have captured the first evidence of a white dwarf, the stellar remnant left over when smaller stars die, coming back to life while feeding on a companion star. The team, led by Durham ...

Black hole accretion processes remain at the forefront of astrophysical research, offering critical insights into how matter is captured by these extreme objects. Accretion occurs when gas, dust, and ...

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 ...

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 ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star ...
