Viscous Heating and Boundary Layer Accretion in the Disk of Outbursting Star FU Orionis
Viscous Heating and Boundary Layer Accretion in the Disk of Outbursting Star FU Orionis
Context. FU Orionis is the archetypal FUor star, a subclass of young stellar object (YSO) that undergo rapid brightening events, often gaining 4-6 magnitudes on timescales of days. This brightening is often associated with a massive increase in accretion; one of the most ubiquitous processes in astrophysics from planets and …
