THE PHYSICAL MECHANISM behind M DWARF METALLICITY INDICATORS and the ROLE of C and O ABUNDANCES Open
We present near-infrared (NIR) synthetic spectra based on PHOENIX stellar atmosphere models of typical early and mid-M dwarfs with varied C and O abundances. We apply multiple recently published methods for determining M dwarf metallicity …

A Physically Motivated and Empirically Calibrated Method to Measure the Effective Temperature, Metallicity, and Ti Abundance of M Dwarfs Open
The ability to perform detailed chemical analysis of Sun-like F-, G-, and K-type stars is a powerful tool with many applications, including studying the chemical evolution of the Galaxy and constraining planet formation theories. Unfortuna…

Magnetic Inflation and Stellar Mass. V. Intensification and Saturation of M-dwarf Absorption Lines with Rossby Number Open
In young Sun-like stars and field M-dwarf stars, chromospheric and coronal magnetic activity indicators such as Hα, X-ray, and radio emission are known to saturate with low Rossby number (Ro ≲ 0.1), defined as the ratio of rotation period …

The Effects of Telluric Contamination in Iodine-calibrated Precise Radial Velocities Open
We characterized the effects of telluric absorption lines on the radial velocity (RV) precision of stellar spectra taken through an iodine cell. To isolate the effects induced by telluric contamination from other stellar, instrumental, or …

Detailed Chemical Analysis of M Dwarf Stars Open
M dwarf stars are the most abundant stars in the Galaxy and appear to host the vast majority of temperate, Earth-sized planets. Investigations into their detailed compositions are important for inferring the chemical evolution of the Galax…

An Empirical Template Library of Stellar Spectra for a Wide Range of Spectral Classes, Luminosity Classes, and Metallicities Using SDSS BOSS Spectra Open
We present a library of empirical stellar spectra created using spectra from the Sloan Digital Sky Survey’s Baryon Oscillation Spectroscopic Survey. The templates cover spectral types O5 through L3, are binned by metallicity from −2.0 dex …

All Spectra Associated With "An Empirical Template Library Of Stellar Spectra For A Wide Range Of Spectral Classes, Luminosity Classes, And Metallicities Using Sdss Boss Spectra" Open
Zip files of all the individual SDSS BOSS spectra. They are sorted by metallicity, luminosity class and spectral type, where each zip file contains all the original SDSS spectra to be co-added into each template. The fits files are in the …

The Physical Mechanism Behind M Dwarf Metallicity Indicators And The Role Of C And O Abundances Open
Recently, numerous methods for measuring [Fe/H] in M dwarf stars have been published. Some methods now claim <0.1 dex precision despite the fact that they do not directly probe Fe abundance. We present an investigation of NIR synthetic M d…
