Comparison of nominal Solar System simulations without surface ablation (top panels), and with surface ablation (bottom panels). The temperature range in the plots is set to 0–300 K to allow for easy comparison; the hottest planetesimals in the top panels have surface temperatures of 443 K, 362 K, and 281 K, respectively, from left to right. The high temperatures obtained in the non-ablation simulations are due to the lack of cooling due to the release of latent heat of vaporization. The population of planetesimals with low eccentricities and short periods in the non-ablation simulations have been circularized by gas drag, these populations do not exist in the ablation simulations since they are removed by ablation before they become circularized.
