| Abstract |
We investigated heating and evaporation of a planetesimal due to planetesimal bow shocks associated with a planetesimal orbiting with supersonic velocity relative to the gas in a protoplanetary disk. We evaluated surface
temperatures and evaporation rates of planetesimals based on the results of the previous studies of planetesimal bow shocks and formation of protoplanets. We found that icy planetesimals evaporate efficiently by bow shock heating in the stage of formation of protoplanets, where strong bow shocks are produced by gravitational perturbations by the protoplanets. |
