A sample of possible red dwarf stars selected using photometric criteria from the 2MASS catalog is being investigated to evaluate the effectiveness of the selection process. Program stars have been identified using the J-H and H-K two-color diagram to identify potential red dwarf stars. Those stars having Tycho2 visual magnitudes have been classified into two groups using the V(T)-K and H-K color indices. Intermediate-band CaH photometry and Kron-Cousins R and I photometry have been obtained at the National Undergraduate Research Observatory (NURO). These data were used to verify luminosity classes for those program stars which are closest to the Sun based on photometric parallaxes. The selection criteria will be discussed. The overall sample of stars selected and the nearby star subset will be described and preliminary results on the effectiveness of the selection process will be presented.
Data for this project were obtained at the Lowell Observatory 31 inch telescope, which, under an agreement with Northern Arizona University and the NURO Consortium, is operated 33% of the time as the National Undergraduate Research Observatory. Funding for this project has been provided by the Indiana Space Grant Consortium, the Arizona Space Grant Consortium, the National Science Foundation REU Program and Ball State University.
