Modeled final density of three KBOs of different sizes formed a different times after CAI. Models are shown with fm=0.70 or 0.50 and with an initial temperature of 40 K. If any small (~100 km-scale) KBOs formed earlier than 4 Myr after CAI the heat from short lived radioisotopes would remove a significant fraction of their internal porosity.
