Spiral shock heating in protoplanetary disks: effect on the water snowline

The location of the water snowline, which is the closest snowline to the star, has an important effect on the formation of planets and their composition. The location of the snowline depends strongly on the heating processes inside the disk. In addition to irradiative heating and viscous heating, we show that heating via spiral shocks emerging from an embedded high mass planet can also have a significant effect on the location and shape of the snowline, sometimes moving it outward by a factor of two.
