[Mesa-users] [EXT] How to check a nuclear reaction rate?

[Cao, Kaili]

Dear Mathieu,

Thank you very much for your quick reply! The `show_rates` script is very handy.

For those who are interested, I checked several values and found a slight disagreement between MESA and JINALAB. I will think more about this.

Cheers,
Kaili

Dear Kaili, there is a way to have MESA print out in a txt file the value of the rate used for a specific reaction as a function of T. This requires using a small script called `show_rates` to convert rates cached in binary format into a human-readable

Dear Kaili,

there is a way to have MESA print out in a txt file the value of the rate used for a specific reaction as a function of T. This requires using a small script called `show_rates` to convert rates cached in binary format into a human-readable format. The script is available in $MESA_DIR/rates/test, see also the relevant section in the documentation<https://urldefense.com/v3/__https://docs.mesastar.org/en/latest/net/nets.html*inspect-the-temperature-dependence-of-used-rates__;Iw!!KGKeukY!0QlmTdnJvC0E1CaZrSUz7TvYvpiV-rjmVoz9yx6tnS8Bq_rNHy-Qb3j8dCKZJbXvYMrjHylRUXvL-uRn3JfLrjyeo4yp7N0$>.

Hope this helps!
Mathieu (with many thanks to Rob Farmer who taught me how to do this)

Dear MESA Users,



Thank you for reading this email.



I would like to ask about how to check a nuclear reaction rate used in MESA, specifically the proton capture rate of 14N, which was halved in 2006 and is important for my purposes.



I understand that the jina_reaclib_filename control is default to "current standard version," but I find the corresponding file (jina_reaclib_results_20171020_default) hard to decipher, and I wish to make a direct comparison to:

https://reaclib.jinaweb.org/n14(p,g)o15/im05/<https://urldefense.com/v3/__https://reaclib.jinaweb.org/n14(p,g)o15/im05/__;!!KGKeukY!0QlmTdnJvC0E1CaZrSUz7TvYvpiV-rjmVoz9yx6tnS8Bq_rNHy-Qb3j8dCKZJbXvYMrjHylRUXvL-uRn3JfLrjyefN_wm2c$>



Can someone please confirm that this rate is up to date, or instruct me how to check it? Thanks a lot.



Best regards,

Kaili Cao
