AM CVn Stars and Accreting White Dwarfs

AM CVn stars represent a striking class of ultracompact binaries in which a white dwarf accretes helium-rich material from a degenerate or semi‐degenerate companion. These systems serve as natural ...

Intermittent black hole jets are like a 'cosmic volcano'

When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they're dormant. They're actively accreting only a tiny amount of matter and ...

Rapidly growing black hole raises new questions about accretion limits

A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.

Artists always show a black hole’s accretion disk oriented in one plane. But stars near Sagittarius A* orbit in a variety of planes. If each of those stars is eventually ...

The answer here is that reality is far more complex than the pictures you reference. At present, our technology does not allow us to get a clear snapshot of the material accreting onto Sagittarius A* ...
