Temperature evolutions at the centers of icy planetesimals with the additional heat source 60Fe (60Fe/56Fe = 1.5 × 10−7(dot-dashed line) and 60Fe/56Fe = 0.8 × 10−8(dotted line)) and without 60Fe (solid line). Results for models of 100-km radius (thick line) and 50 km radius (thin line) formed at 1.0 Myr after CAI formation with 150K for the initial temperature are shown. The abscissa, the ordinate and the horizontal dotted lines are the same as in Fig. 5. Results with 60Fe/56Fe = 0.8 × 10−8, and without 60Fe, are almost the same and those lines overlap.
