Title: Confirmation of Young Stars Near the Sun

Abstract: Using a chi-squared spectral energy distribution fit of $VRI$, 2MASS $JHK$, and WISE data to the BT-Settl model grid, we are characterizing a total of 1874 of the nearest red dwarfs by providing systematically determined luminosities, T$_$, and radii. One result of this program is the identification of young/old stars via their correspondingly large/small radii. Radii for these stars can be used as proxies to map stellar ages for stars in the solar neighborhood from which we can piece together our Galaxy's history. As part of the PI's PhD thesis, we wish to gather short-term variability data for 15 candidate pre-main sequence stars to serve as indicators of these stars' youth.
