An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. The central...

protoplanetary disk may also be considered an accretion disk for the star itself, because gases or other material may be falling from the inner edge of the disk onto...

protoplanetary disk evolving into a planetary system over the next 10–100 million years. The protoplanetary disk is an accretion disk that feeds the central...

into an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes. The accretion model that...

A circumstellar disc (or circumstellar disk) is a torus, pancake or ring-shaped accretion disk of matter composed of gas, dust, planetesimals, asteroids...

wind from the star provides material for an accretion disk around the X-ray source. Matter in the inner disk is heated to millions of degrees, generating...

light. Any matter that falls toward a black hole can form an external accretion disk heated by friction, forming quasars, some of the brightest objects in...

hours to render, totaling 800 terabytes of data. Thorne described the accretion disk of the black hole as "anemic and at low temperature—about the temperature...

black hole can reach, while being luminous accretors (featuring an accretion disk), is typically on the order of about 50 billion M☉. However, a 2020...

photons emitted by the accretion disk. A less exotic means would be to simply capture photons already escaping from the accretion disk, thereby reducing a...
