Asteroseismic Inversions for Internal Sound Speed Profiles of Main-sequence Stars with Radiative Cores

This repository contains the accompanying inlists and run_star_extras files for Buchele et al. (2024):  Asteroseismic Inversions for Internal Sound Speed Profiles of Main-sequence Stars with Radiative Cores.

The MESA version used is r22.05.1. We have modified the /star/private/pulse_fgong.f90 file in the MESA source code to output the Gamma1 derivatives that are necessary to compute u-Y kernels by replacing the file with the version from https://github.com/MESAHub/mesa/pull/431. Additionally, we use the MESA SDK versions 22.6.1 and the GYRE version 6.0 that is included with the r22.05.1 release of MESA. 

The directory grid_base contains the inlist which set the parameters that do not change across the tracks of our grid

Inlist_all includes parameters that are constant across all tracks and evolutionary stages 

Inlist_prems includes parameters for the pre-main sequence evolution of all tracks 

Inlist_ms includes parameters for the main sequence evolution of all tracks 

run_star_extras.f90 includes the code which stops the evolution of a track when the central hydrogen abundance reaches the target value 

gyre.in includes parameters for calculating of frequencies using GYRE

The directory reference_models provides the inlists to generate our reference model for each star in our sample. This directory also includes the FGONG structure files of the computed reference models. Each file is labeled with the identifier used in the text, typically the KIC number. 

The physics_tweaks directory provides the inlists to generate the models with modified input physics. The suffixes refer to the physics that was changed in each model, as follows: 

core_kap:  Core opacity

pp2: change to the He3+He4->Be7 reaction rate

cno: change to the N14 + p -> O15.
