Input and output files for "Merger seismology: distinguishing massive merger products from genuine single stars using asteroseismology" (Henneco et al. 2024b)

This repository contains the MESA and GYRE input files required to reproduce the models used in Henneco et al. (2024b), as well as some of the output files.

[MESA version]
MESA r12778
MESA SDK 20.3.2

[GYRE version]
GYRE 7.0
MESA SDK 22.6.1

input_files

This directory contains the template input files for the MESA and GYRE models.

gyre

- gyre_nonrot_template.in: GYRE inlist for computations without rotation
- gyre_rot_template.in: GYRE inlist for computations, including rotation using the TAR
- gyre_rot_pert_template: GYRE inlist for computations including rotation using the perturbative approach

mesa

- genuine_single: MESA work directory for genuine single stars
- merger_product: MESA work directory for merger products via the fast accretion method
- zams_z0142_y2703.data: ZAMS models used to start all MESA computations from

output

mesa

In this directory, we provide the MESA history and profile (GYRE format only) output for the MESA models used in our work.
The more detailed regular profile files are left out because of storage constraints, but these can be transferred upon reasonable request.

- mXX_plus_mYY_at_rZZ: XX + YY Msol merger product model where the fast accretion method was invoked when the HG star had a radius of ZZ Rsol
- mXX: genuine single-star model of XX Msol

gyre

This directory contains the GYRE summary files and input files (with the frequency ranges specific to these models). The detail files are left out because of storage constraints, but these can be transferred upon reasonable request. 

[suffixes]
NAD: nonadiabatic computations
pmodes: computations in frequency ranges appropriate for pressure modes
Om20_PERT: computations including rotation (20% of critical) using the perturbative approach
Om20_TAR: computations including rotation (20% of critical) using the TAR

Except for the computations in `m6.0_plus_m2.4_at_r9.0`, the GYRE computations have been made only for a specific MESA profile (the profile at the time when the models were seismically compared).
These are:

- m6.0_plus_m2.4_at_r9.0: profile 38
- m7.8: profile 14
- m9.0_plus_m6.3_at_r10.4: profile 62
- m13.6: profile 16

For the `m6.0_plus_m2.4_at_r9.0` model, GYRE computations have been made for profiles 27 -- 52 (see Section 4.2).
