Planet migration in wind-fed accretion discs in binaries

Abstract: Planet migration originally refers to protoplanetary disks, which are more massive and dense than typical accretion disks in binary systems. We study planet migration in an accretion disk in a binary system consisting of a solar-like star hosting a planet and a red giant donor star. The accretion disk is fed by a stellar wind. We use the αdisk model and consider that the stellar wind is time-dependent. Assuming the disk is quasi-stationary we calculate its temperature and surface density profiles. In addition … Show more

“…As the disc is formed from the stellar wind matter, its properties depend on the mass loss rate by the donor and parameters of the binary. In this study we advance the analysis initiated by Kulikova et al (2019). We use a numerical model to calculate properties of non-stationary discs (NSD) with a variable mass inflow on the whole disc surface within the Bondi radius during late stages of the primary evolution.…”
