Temperature profile for the midplane of a static disk (solid red line) and an accreting and irradiated protoplanetary disk (solid blue line). The horizontal dashed line shows the position of the snow line considering a value of 170 K for the sublimation temperature of water ice. The edges of the corresponding snow lines are indicated with dotted vertical lines and their distances. The separation of the planets in the system is also shown as a reference. The size of the symbols is proportionalto the planetary masses.
