Hi JC —

We’ll have to see your inlist_astero_search_controls as well — many of the values specified there will override those specified in inlist_solar.

cheers,

I obtain the figures below, which show a significant increase in the two quantities I chose to plot (effective temperature and luminosity). I did that using *.mod files but I found the same behavior with the photos.
