M Dwarf Atomic and Molecular Features in SDSS DR7 Spectra
Abstract
Large, homogenous spectroscopic datasets offer the opportunity to investigate the behavior of stellar atmospheres as a function of various stellar parameters with unprecedented statistical accuracy. We use the SDSS DR7 spectroscopic catalog of 70,000 low mass stars to investigate the changes in atomic and molecular features that occur with differing mass, temperature, metallicity, and level of magnetic activity.
