Thermodynamics over the Web

Get thermodynamics values for any combination of temperature, density and hydrogen mass fraction using MHD, OPAL or ISG equations of state.

Server runs on Dual Celeron 466MHz with 16MB of RAM, so please be patient.

Currently, allowed ranges are as follows:
Temperature3.0 < lg T < 7.5
Density function-2.0 < lg Q < 1.0
Hydrogen abundance0.2 < X < 0.8
Heavy elements abundance0.010 < Z < 0.025
Q is rho/(T/10^6)**3, i.e. lg Q = lg rho + 18.0 - 3.0 * lg T
