Kiauhoku Stellar Evolutionary Model Grids

Creators

  • 1. Institute for Astronomy, University of Hawaii

Description

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. in prep. 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).

Notes

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.
