[mesa-users] 35Cl and K39

[Roni Waldman]

Hi Dave,

I used the ns_he.net which was provided with MESA.

I just naively supposed it has been tested by someone who devised it.

I attach a file containing the list of nuclei and reactions in the net.

 

Let me clarify, if you are saying that for Si burning you need ~60 isotopes,
then do you mean that the approx21 network which is standard in MESA (see
attached file) is also wrong?

It was my understanding that it is possible to devise small effective
networks which give the energy production correctly, without getting stuck
into an unrealistic composition.

Am I wrong?

 

Thanks for your help.

Roni

Hi Roni,

It depends on your network (which was removed from the email post, so I
can't see it).  How may nuclei do you have? For Si burning you need ~60

as a rule, to get the quasi-equilibrium right. With fewer, mass goes to
strange places because of constraints on charge and nucleon number.

Maybe you should send more info offline.

Dave
