摘要: Thermal evolution models for asteroids that experienced metamorphism (ordinary chondrites), aqueous alteration (carbonaceous and melting differentiation (HED achondrites) are compared. These models, based on decay of 26Al, can be used to study a variety asteroidal processes such as the insulating effect regolith, buffering ice fluid flow, complications arising from redistribution heat sources during differentiation. also account an apparent relationship between peak temperature heliocentric distance in main belt. using other (electromagnetic induction, collisions) poorly constrained at this point have been primarily simple plausibility calculations.
