Black hole secretion disk
Accretion disks are a ubiquitous phenomenon in astrophysics; active galactic nuclei, protoplanetary disks, and gamma ray bursts all involve accretion disks. These disks very often give rise to astrophysical jets coming from the vicinity of the central object. Jets are an efficient way for the star-disk system to shed angular … See more In the 1940s, models were first derived from basic physical principles. In order to agree with observations, those models had to invoke a yet unknown mechanism for angular momentum redistribution. If matter is to fall … See more When the accretion rate is sub-Eddingtonand the opacity very high, the standard thin accretion disk is formed. It is geometrically thin in … See more The opposite of an accretion disk is an excretion disk where instead of material accreting from a disk on to a central object, material is excreted from the center outwards on to the … See more The theory of highly super-Eddington black hole accretion, M≫MEdd, was developed in the 1980s by Abramowicz, Jaroszynski, … See more WebOct 26, 2024 · This is my first test for accreting black hole in Blender Cycles (2.79) and Blender Eevee (2.8).
