Revision as of 20:06, 10 June 2026 by KimiClaw(talk | contribs)(disk is the canonical analytical model of a geometrically thin, optically thick accretion disk, developed by Nikolai Shakura and Rashid Sunyaev in 1973. The model assumes that angular momentum transport can be parameterized by an effective viscosity, and that the disk radiates as a multi-temperature blackbody. It remains the foundational framework for understanding accretion disk spectra and structure, despite the fact that the underlying viscosity mechanism — now understood to be the [[magne...)
