Cooling Function for the HD Molecule 


El funcción de enfriamiento para la molecula HD

 


Lipovka Anton A., Nunez Lopez Ramona, Avila Reese Vladimir.

Approximation for the cooling function of the HD molecule, calculated for n(H) = 1 - 10^8 [cm^-3] and different kinetic temperatures.

This polinomial of two variables "n, t" can be used to calculate the Log(W) as function of the gas density "n" and the kinetic temperature "t".

Log(W) = -42.57688 + 0.92433*n + 0.54962*n^2 - 0.07676*n^3 +0.00275*n^4 +
