| Abstract: |
We present a spectroscopic catalog of 70,841 visually inspected M
dwarfs from the seventh data release (DR7) of the Sloan Digital Sky
Survey (SDSS). For each spectrum, we provide measurements of the
spectral type, a number of molecular bandheads, and the Hα,
Hβ, Hγ, Hδ and Ca II K emission lines. In
addition, we calculate the metallicity-sensitive parameter ζ
and 3D space motions for most of the stars in the sample. Our
catalog is cross-matched to Two Micron All Sky Survey (2MASS)
infrared data, and contains photometric distances for each
star. Future studies will use these data to thoroughly examine
magnetic activity and kinematics in late-type M dwarfs and examine
the chemical and dynamical history of the local Milky Way. |
