Korg: a modern 1D LTE spectral synthesis package
Adam J. Wheeler, Matthew W. Abruzzo, Andrew R. Casey +1
We present Korg, a new package for 1D LTE (local thermodynamic equilibrium) spectral synthesis of FGK stars, which computes theoretical spectra from the near-ultraviolet to the nea…
The homogeneity of the star forming environment of the Milky Way disk over time
Melissa K. Ness, Adam J. Wheeler, Kevin McKinnon +4
Stellar abundances and ages afford the means to link chemical enrichment to galactic formation. In the Milky Way, individual element abundances show tight correlations with age, wh…
HARPS Abundances with Korg I: 22 Element Abundances for 426 Red Giant Stars
Sarah E. Aquilina, Melissa Ness, Adam J. Wheeler +1
Large stellar surveys have revealed the global abundance structure of the Milky Way, but small high-fidelity spectral samples offer a critical complement of nucleosynthetic depth.…
Improving Radial Velocities by Marginalizing over Stars and Sky: Achieving 30 m/s RV Precision for APOGEE in the Plate Era
Andrew K. Saydjari, Douglas P. Finkbeiner, Adam J. Wheeler +7
The radial velocity catalog from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) is unique in its simultaneously large volume and high precision as a result of…
