Stellar evolutionary model grids for use with Python Kiauhoku package (presented by Claytor et al. 2020). This dataset contains models from MIST, YREC, GARSTEC, and Dartmouth projects. Model Grids fastlaunch Originally presented by Claytor et al. (2020). Computed using the Yale Rotating stellar Evolution Code (YREC, Pinsonneault et al. 1989) with rotational evolution computed separately using the magnetic braking law of van Saders and Pinsonneault (2013) under "fast launch" condition of Pinit ~ 8 days. slowlaunch Originally presented by Claytor et al. (2020). Computed using the Yale Rotating stellar Evolution Code (YREC, Pinsonneault et al. 1989) with rotational evolution computed separately using the magnetic braking law of van Saders and Pinsonneault (2013) under "slow launch" condition of Pinit ~ 13 days. rocrit Originally presented by Claytor et al. (2020). Computed using the Yale Rotating stellar Evolution Code (YREC, Pinsonneault et al. 1989) with rotational evolution computed separately using the stalled magnetic braking law of van Saders et al. (2016) under "fast launch" condition of Pinit ~ 8 days. mist Evolutionary tracks from the MESA Isochrones and Stellar Tracks (MIST, Choi et al. 2016). Computed using Modules for Experiments in Stellar Astrophysics (MESA, Paxton et al. 2010). yrec Originally presented by Tayar et al. (2022). Computed using the Yale Rotating stellar Evolution Code (YREC, Pinsonneault et al. 1989). dartmouth Originally presented by Dotter et al. (2008). Models from the Dartmouth Stellar Evolution Program (DSEP). garstec Originally presented by Serenelli et al. (2013). Computed using the Garching Stellar Evolution Code (GARSTEC, Weiss & Schlattl 2008).

v. 2.1.1 Resampled EEPs for YREC, GARSTEC, and Dartmouth grids, following Morales et al. (2025). v. 2.1.0 added the full available MIST EEP tracks, rather than just a subset. v. 2.0.3 fixed a minor bug in the YREC EEP tracks for M/Msun >= 1.8 that mistook the TRGB as the RGB bump. Removed the bump as an EEP; now all tracks (save one, M/Msun = 0.7, [Z/X] = +0.5) correctly reach the TRGB. fixed critical bug from v. 2.0.2. v. 2.0.2 [DEPRECATED: critical bug in the yrec_eep.tar.gz file, where kiauhoku would download it, not realize it downloaded, and infinitely try to download again. This bug is only present in v 2.0.2] v. 2.0.1 updated Dartmouth and Garstec EEP grids to extend to RGBTip. v. 2.0 updated directory structure for compatibility with kiauhoku v. 2.0. v. 1.3 src and eep files provided for individual model grids. v. 1.2 bug fixed in Dartmouth (DSEP) grid that affected placement of Terminal Age Main-Sequence EEP in ~25% of tracks. v. 1.1 grids are identical, but added separately downloadable interpolators and grids, as well as an option for bulk download.
