Mass Estimates of a Giant Planet in a Protoplanetary Disk from the Gap Structures

Kazuhiro D. Kanagawa, Takayuki Muto, Hidekazu Tanaka +4

A giant planet embedded in a protoplanetary disk forms a gap. An analytic relationship among the gap depth, planet mass $M_p$, disk aspect ratio $h_p$, and viscosity $\alpha$ has been…
