asteroid size How large should be the body so that the maximal internal temperature reaches given temperature Tm (melting temperature)? I'm thinking i can use F= K*[(Ta-Tb)/(Ra-Rb)]. where F is heat flux, K is thermal conductivity, T is change in temperature and R is change in depth. I'm...

the units for that would be W/m^3. this is almost heat flux (W/m^2). where would i go from there?

well i know heat flux = -k(dt/dr) this is change in temperature with depth and thermal diffusivity x= k/pC (here p is density and C is heat capacity). I just don't know how to apply heat production. I feel like I'm missing an equation and i have no idea what it is.

Consider main-belt chondritic asteroids. How large should be an asteroid so that the maximal internal temperature exceeds the melting temperature of ice? Of rocks? For your calculations, use the present-day chondritic heat production w = 4×10-12 W kg-1, typical thermal conductivity of...
