Calibrating M Dwarf Metallicities Using Molecular Indices
Calibrating M Dwarf Metallicities Using Molecular Indices
We report progress in the calibration of a method to determine cool dwarf star metallicities using molecular band strength indices. The molecular band index to metallicity relation can be calibrated using chemical abundances calculated from atomic‐line equivalent width measurements in high‐resolution spectra. Building on previous work, we have measured Fe …
