Abstract:
Hydrodynamic processes in protoplanetary disks influence a number of key stages in planet formation and evolution. One candidate, the Convective Overstability may operate in planet-forming disk regions. I will present our group’s recent efforts in modeling the COS using a variety of frameworks to test its robustness and explore its implications for planetesimal formation and planet migration. This includes the local Boussinesq approximation, global compressible simulations, with and without dust, an ongoing “locally global” setup, and extensions to magnetized gas. I will discuss the advantages and caveats of each approach, and suggest future directions.
Biography:
Dr. Min-Kai Lin is an Associate Research Fellow at the Academia Sinica Institute of Astronomy and Astrophysics. He completed his PhD in 2011 at the University of Cambridge, followed by a postdoctoral fellowship at the Canadian Institute for Theoretical Astrophysics from 2011 to 2014, and was a Steward Theory Fellow at the University of Arizona from 2014 to 2016, before taking up his current faculty position at ASIAA. Dr. Lin's primary expertise is astrophysical fluid dynamics applied to theories of planet formation and evolution.
