Photoevaporation With Protoplanetary Disks
... of the disk gives rise to a stability length scale known as the gravitational radius ... Outside of the gravitational radius, particles can become sufficiently excited to escape the gravity of the disk, and evaporate ... The formula for the gravitational radius of the disk is where is the ratio of specific heats (= 5/3 for a monatomic gas), the universal gravitational constant, the mass of the central star ...
The Lemaître Coordinates
