On this page you can compute thermodynamics
for conditions which exist inside the Sun. Different equations of state
tables can be used, including SAHA-S equation of state.
If you do not select anything, pressure will still be printed.
Enter here temperature T, density rho and chemical composition,
one set of values per line (multiple lines are allowed). Chemical composition
can be entered in four possible ways:
1) separate input fields for X and Z are used, each line contains only T and rho;
2) each line contains T, rho, X and Z; separate input fields for X and Z are
2.17e6 0.18 0.74 0.018
3) each line contains T, rho, X, Z(CNO), Z(Ne), Z(FeSi); separate input fields
for X and Z are ignored; example:
2.17e6 0.18 0.74 0.010 0.002 0.006
4) each line contains T, rho, X and 19 components for Z (C, N, O, Ne, Na, Mg,
Al, Si, P, S, Cl, Ar, K, Ca, Ti, Cr, Mn, Fe, Ni); separate input fields
for X and Z are ignored (this format is not very useful currently)
It is possible but not recommended to mix different numbers of Z components in one job.
Input field size does not limit the amount of data entered; you can type or paste
thousands of lines (10,000 lines tested with output size over 5MB).
Hydrogen mass fraction X (0.0 - 0.9):
Heavy elements mass fraction Z (0.0 - 0.02):
EOS tables may take up to 20 seconds to load! Please be patient...
