[Mesa-users] The evolution after log T_c > 9.85 for presupernova

[辛文宇]

Hi,




I've calculated the evolution of presupernova from ZAMS with mesa-r12778.

The calculation with  "inlist_to_lgT_9.9" stop at log T_c = 9.85, then "inlist_finish"

is used for the folowing evolution. The evolution in T-Rho diagram (final_trho.pdf)

is the black line.

I noticed that these two:

eps_nuc_factor = 0d0

dxdt_nuc_factor = 0d0

are used in inlist_finish. The nuclear burning is turn off artificially. Thus I uncomment

those and trun on the nuclear burning. The evolution becomes the green line in final_trho.pdf.

It seems strange. I also try to remove the "inlist_finish" and continue the following evolution 

with "inlist_to_lgT_9.9", which is red line in the final_trho.pdf.

The Kippenhahn diagram of green and  red line are also attached.

Here are questions. 

With nuclear burning, why "inlist_finish" and "inlist_to_lgT_9.9" show such large differences?

How the following evolution is treated differently in "inlist_finish"?

All these three lines seems strange, so how we treat the evolution before pre-SN in MESA.




Thanks,

Wenyu
