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 ...

Stars are born in clouds of gas and dust, making it difficult to observe their early development. But researchers at Chalmers have now succeeded in simulating how a star with the mass of the sun ...

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 ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

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 ...
