[mesa-users] Mesa sound speeds

[Bill Paxton]

I just checked my recent run of the example_solar_model test case -- the comparison plot of sound speed from the model compared to the data from BP98.  I include BP98 data and the profile from mesa.

Here's a better plot i made previously. one is both plotted against each other. and the other is the actualy sound speed difference plot. it look coherent for low radii but diverges very quickly. the x axis is raidus. one is my mesa cspeed, the other is healioseismic data.  This data looks different due to some scaling on the y-axis.   Ignoring the previous plot i sent, which uses fortan type inerpolations, does the diveregence i'm talking about make sense? the sound speeds seem way too high for large radii
