•From theory:
–Pressure (P) and density (r)
must increase with depth
•Weight of overlying gas compresses lower material -- “Hydrostatic equilibrium”
–Temperature (T) must increase with depth
•Energy is flowing out of the sun – and it flows from
hot to cold -- so hot inside
–Numerical modeling of details let us calculate T(r), r(r), P(r)
