Temperature evolutions at the centers of planetesimals for models 10–10B (dot-dot-dashed line), 50–10B (dashed line), 100–10B (dot-dashed line), 500–10B (solid line) and 1000–10B (thick dotted line). The abscissa, the ordinate and the horizontal dotted lines are the same as in Fig. 5. The results of 500–10B and 1000–10B are almost same and those lines overlap.
