Notes. 
are the ambient values of the density, bulk modulus, polytrope exponent, Gruneisen parameter, and its derivative, respectively. A is the mean atomic number and Z is the mean proton number. tmin and δt are the t-model parameters. Tl is the temperature at the end of the layer and rl is the outer radius of the layer. M = 5.97 × 1024 kg, PC = 364.1 GPa, TC = 5300 K.
