Fig. 5From: Thermal evolution of icy planetesimals in the solar nebulaTemperature evolutions at the centers of planetesimals for models 10–10A (dot-dot-dashed line), 50-10A (dashed line), 100–10A (dot-dashedline), 500–10A (solidline) and 1000–10B (thick dotted line). The abscissa shows the time after CAI formation in units of a million years and the ordinate shows the temperature at the center in kelvin. The horizontal dotted lines represent the temperature at which the chemical reactions take place: 273 K (ice melting and aqueous alteration) and 873 K (the dehydration reaction). The results of 500–10A and 1000–10A are almost the same and those lines overlap.Back to article page
