The accretion disc eclipse mapping method is an astrotomographic inversion technique that makes use of the information contained in eclipse light curves to probe the structure, the spectrum and the time evolution of accretion discs in cataclysmic variables. This paper presents examples of eclipse ...
This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. Credit: ESA/Hubble, ESO, M. Kornmesse Origin of Theory: Singularities were first predicated as a result of Einstein’sTheory of General Relativity, which resulted in the theoretical existenc...
Accretion disc! Planetary formation! Evolutionary patterns and processes! Neuroscience! Archaeology! Read some scientific articles, informative magazines, based on evidence! Read scientific books and listen to audio-books. There's so much you can learn. And possibly you've already learned something, ...

Quasars tend to have accretion discs of gas and dust; when material from the disc falls into the Quasar, it is ejected as electromagnetic radiation. Once the accretion disk is used up, it becomes passive. Quasars tend to be at the centres of galaxies far, far away....
An example of the difficulties in deriving He abundance variations from clusters with red horizontal branch is given by a comparison of the spread in He abundances for the SMCs clusters NGC 121, NGC 339, NGC 416, and Lindsay 1 as determined from the horizontal branch by Chantereau et al. ...
Artist’s impression of the early Solar System, where collisions between particles in an accretion disc led to the formation of planetesimals and eventually planets. Credit: NASA/JPL-Caltech First, there is the amount of energy it would have required to destroy a planet, which would have been...
For holes that are small enough to spaghettify you before you reach the horizon, the only risk of which you can be aware is radiation from the accretion disc: both spaghettification and blue-shifted CMB last for such a short time that you will be dead before you notice. ...
An artist's impression of the accretion disc around the supermassive black hole that powers an active galaxy. Astronomers want to know if the energy radiated from a black hole is caused by jets of material shooting away from the hole, or by the accretion disk of swirling material near the ...
Now, the black hole recap. Naturally formed when the largest stars, those with more than 20 times the mass of the Sun, collapse violently and explode. Here the density of matter is so high, the escape velocity exceeds the speed of light. The fancy ones have a super-heated accretion disk...
