Multilayer dripping handrail: Modeling accretion disk dynamics with cellular automaton leaky faucet model

We study the behavior of a Multilayer Dripping Handrail model of the accretion disk, which is based upon a cellular automaton approach inspired by Yonehara et al. (1997). In combination with the Mass–Spring model of a leaky faucet system first proposed by Shaw (1984) and later modified by Kiyono and...

Description
Summary:	We study the behavior of a Multilayer Dripping Handrail model of the accretion disk, which is based upon a cellular automaton approach inspired by Yonehara et al. (1997). In combination with the Mass–Spring model of a leaky faucet system first proposed by Shaw (1984) and later modified by Kiyono and Fuchikami (1999). Mass–Spring model serves the purpose of critical condition for the dripping mechanism redistributing accreting mass into lower disk annuli. As falling matter loses energy, we model the accretion disk’s temperature distribution and radiative output. Our primary focus is on modeling the temperature distribution changes, of which the main manifestation is the flickering in extracted synthetic light curves.
