DESCRIPTION:The passage of heat throughout a planetary body is one of the 
 fundamental processes that drives their long-term behaviour and evolution.
  The textures and compositions of different meteorites demonstrates that a
 steroids contained different amounts of heat\, and as such displayed very 
 different thermochemical evolutions. In this talk\, I will present model r
 esults of the thermal evolution of different asteroids with the aim of unc
 overing how these bodies generated and transported heat. I will also use t
 hese results to predict when different asteroids could have generated magn
 etic fields through core dynamo activity. I will compare the models result
 s with the textures and the magnetic remanences carried by a number of met
 eorites to recover some key properties of the parent asteroids of differen
 t meteorite groups. These results elucidate the key processes that occurre
 d with asteroids and the physical properties that controlled how these bod
 ies behaved across their active lifetimes.
