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

<p>Evolutionary tracks generated with MESA accompanying the project &nbsp;<br>``Stellar Evolution in Real Time II: R Hydrae and an Open-Source Grid of &gt;3000 Seismic TP-AGB Models Computed with MESA'' ApJ 2024</p> <div> <p>Due to data volume, this is one of four Zenodo repositories associated to this project. The full list of related dataset DOIs is:</p> <ul> <li>https://doi.org/10.5281/zenodo.11280179</li> <li>https://doi.org/10.5281/zenodo.11282597</li> <li>https://doi.org/10.5281/zenodo.11353933</li> <li>https://doi.org/10.5281/zenodo.11357395</li> </ul> <p><strong>Details on archive files:</strong></p> <p>All phase 1 and phase 2 evolutionary tracks are contained in the files</p> <p>ZAMS_to_TCHeB_y-fixed.tar.gz<br>TCHeB_to_AGB_y-fixed.tar.gz<br>ZAMS_to_TCHeB_y-varied.tar.gz<br>TCHeB_to_AGB_y-varied.tar.gz</p> <p>sorted by whether a varied or static helium assumption was used.</p> <p>To use the smallest number of separate Zenodo listings possible, not all data are grouped in the same way.</p> <p>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.</p> <p>Archive files labeled in the form "AGB_to_end_M1.XX_y-varied.tar.gz" include the same, but using the helium-varied assumption.&nbsp;</p> <p>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).</p> <p>&nbsp;</p> <p><strong>Details on files unpacked from archives:</strong></p> <div>Every unpacked file has a name of the form&nbsp;</div> <div>&nbsp;</div> <div>history_m4.90_z0.0060_y0.261_eta0.01_yi-on_seismic_p3.data</div> <div>&nbsp;</div> <div>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.</div> <div>&nbsp;</div> <div>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&nbsp; to the onset of the asymptotic giant branch (AGB).<br><br>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.&nbsp;</div> <div>&nbsp;</div> <div>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.&nbsp;</div> </div>
