[mesa-users] [MESA]: Question Astrophysical Factor

[Gonçalo Andrade]

Dear Sir or Madam,



I'm a MSc student and I'm doing my master thesis on asteroseismology of red giant stars. I'm using MESA to do models of these stars.


I found this email on the MESA community website and I decided to try it as a last resource.


The thing I need to do now in my project is to change the Astrophysical Factor (S-Factor) from the pp nuclear reaction to try to find out what changes does it have in the star and if these can be measured using seismology. The problem is I've been been searching online for some weeks and I can't find out how to change this factor. I've tried several things, the closest to what I wanted, I think, was to change the value on the file $MESA_DIR/rates/private/ratelib.f90 , but after that change the code no longer compiles...


I a few words, I just need to change the S-Factor of the pp reaction.



I thank you in advance and hope I'm not being inconvenient.


Yours faithfully,

Gonçalo Andrade
