"Saving Low-mass Planets in Dusty Protoplanetary Disks"
時間/地點: 2020-12-18 14:00 [S4-1013]
摘要:
In standard, gas-dominated disks, low-mass planets undergo rapid inwards migration and are lost to the central star. It is then difficult to explain the enormous low-mass exoplanets discovered so far. Recent studies have shown that in dust-laden disks, various dust substructures could be induced in the vicinity of planet, which could have significant effects on disk-planet interactions. In this talk, I will present 2D two-fluid hydrodynamic simulations and show the migration behavior of low-mass planets in dust-laden disks. I will also discuss the new recovered regime of stochastic migration applicable to disks with abundant large dust particles.
