Measuring 14 Elemental Abundances with R = 1800 LAMOST Spectra

Ting, Yuan-Sen; Rix, Hans-Walter; Conroy, Charlie; Ho, Anna Y.Q.; lin, jane

Description

The LAMOST survey has acquired low-resolution spectra (R = 1800) for 5 million stars across the Milky Way, far more than any current stellar survey at a corresponding or higher spectral resolution. It is often assumed that only very few elemental abundances can be measured from such low-resolution spectra, limiting their utility for Galactic archaeology studies. However, Ting et al. used ab initio models to argue that low-resolution spectra should enable precision measurements of many elemental...[Show more]
