Evolutionary tracks accompanying Stellar Evolution in Real Time II (2/4)

Evolutionary tracks generated with MESA accompanying the project  ``Stellar Evolution in Real Time II: R Hydrae and an Open-Source Grid of >3000 Seismic TP-AGB Models Computed with MESA'' ApJ 2024

Due to data volume, this is one of four Zenodo repositories associated to this project. The full list of related dataset DOIs is:

Details on archive files:

All phase 1 and phase 2 evolutionary tracks are contained in the files

ZAMS_to_TCHeB_y-fixed.tar.gzTCHeB_to_AGB_y-fixed.tar.gzZAMS_to_TCHeB_y-varied.tar.gzTCHeB_to_AGB_y-varied.tar.gz

sorted by whether a varied or static helium assumption was used.

To use the smallest number of separate Zenodo listings possible, not all data are grouped in the same way.

The tar.gz archive files labeled with a string of the form "AGB_to_end_M1.XX_y-fixed.tar.gz" include all models having a mass beginning with 1 (1.00, 1.10, 1.20, etc) and adopting the fixed helium assumption.

Archive files labeled in the form "AGB_to_end_M1.XX_y-varied.tar.gz" include the same, but using the helium-varied assumption. 

Archive files labeled with a string of the form "AGB_to_end_M3.10_all.tar.gz" include both the fixed-helium and varied-helium tracks for all masses that start with 3 (3.00, 3.10, 3.20, etc).

Details on files unpacked from archives:

Every unpacked file has a name of the form 

history_m4.90_z0.0060_y0.261_eta0.01_yi-on_seismic_p3.data

Anything that starts with "history" and ends with ".data" is an evolutionary track. Tracks that have "_p3" are the third phase: AGB to end (or failure of the model) and these files are large.

Tracks that have "_p1" are the evolution from the zero-age main sequence (ZAMS) to the terminal age core helium burning (TCHeB). Tracks that have "_p2" evolve from TACHeB  to the onset of the asymptotic giant branch (AGB).In the file name, the two-decimal number after m, four-decimal number after z and 3-decimal number after y encode the evolutionary track's initial mass, initial metallicity (Z) and initial helium abundance (Y), respectively. In cases where there is no y value provided, the helium abundance is fixed as described in the paper. 

When the file name contains "yi-on" in the name, it means the helium-varied assumption was used. When the file contains "seismic" (should only be the case for p3's), it means the GYRE calculations are included in the output.
