[Mesa-users] nucleosynthesis of PISN

[辛文宇]

Hi, everyone,




I am trying to calculate the nucleosynthesis yields of PISN with the "ppisn" package of mesa-r23.05.1.

the initial He star mass is 102 Msun, Z=0 and I use the network of mesa_128.net.

More detail please check the inlist0.zip.

I also attached the T-rho diagram and the abundance pattern of this test.




The problem is:

Compared with the model in Takahashi 2018 ApJ.875:111,
We have a higher [Si, S, Ar, Ca/Fe], about 1 dex, but lower
[Cl, K, Sc/Fe] also about 1 dex. Specially, we have extremely
higher Co/Fe and Ni/Fe in this model.
I also note that the total mass of 56Fe and Ni56 are 7E-8 and 3.3 Msun
in this model.
It seems that this abundance pattern is before explosion and not that

after PISN explosion. Right? If right, how can we get the nucleosynthesis yields

after explosion?




Thanks,

Wenyu
