Description
Title: Twists and turns in modern planet formation and evolution
Speaker: Min-Kai Lin (林明楷), ASIAA
Abstract:
Planets are formed in gaseous protoplanetary disks around young stars. A bottleneck in modern planet formation theory is how planetesimals — the building blocks of planets — are formed from smaller pebbles. The leading mechanism for planetesimal formation is the streaming instability driven by mutual friction between the gas and embedded solids. However, protoplanetary disks are complicated by a plethora of physical effects neglected in the standard picture of the streaming instability. I will present our group’s recent work generalizing models of the streaming instability to incorporate more realistic treatments of gas dynamics, including turbulence, magnetic fields, and disk structures. I highlight new challenges and potentially new pathways to planetesimal formation. I will also discuss how planet-disk interaction can shape the disk and leave unique features that are only found in fully 3D simulations.
Bio:
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.
