[Mesa-users] Effective temperature in the results of RR Lyrae simulation

[Guzik, Joyce Ann]

Dear Xiao-Wei, et al.


I noticed this low temperature too when running Cepheid models using RSP and looking at the set of dashboard plots and model summary output.  I think that the number reported as the effective temperature in rsp on these plots and output is the temperature of the outermost zone (above the photosphere).  The RSP inlist effective temperature is being used correctly to calculate the model.


Could you look at the result if you calculate the effective temperature using the luminosity and radius values that RSP is producing?  When I calculate effective temperature this way I do obtain reasonable values that vary above and below the inlist T_eff during the pulsation cycle.


Probably these plots should be modified to have a label of surface temperature on the axes and in the output box and in the model summary text at the bottom, or a better alternative is that the the T_eff should be calculated a different way (using L and R) for these plots and output.


Would it be possible to make this change to the test suite examples provided with RSP for future releases?

Hi,

    I'm using rsp_RR_Lyrae part to do the simulation of RR Lyrae stars,  with inlist_rsp_RR_Lyrae of set B in the instrumental paper from 2_rsp.zip file. But it seems weird that every time the effective temperature is much lower than the initial effective temperature I set. For example, if I set initial effective temperature as 7800K, the results I got is around 6500K. Changing initial luminosity, mass and metallicity and convective modes doesn't help. I'm really appreciate it if you can help me. Thank you!


Cheers,

Xiao-Wei
