The luminosity function of low luminosity red stars is important due to the high frequency of such stars and their substantial contribution to the mass of baryonic matter as determined by analysis of the numbers of such stars within a few parsecs of the Sun. Many such stars relatively close to the Sun have not been detected due to their low luminosity and to an inability to distinguish between red giant and dwarf stars.
CCD photometry is being used to detect nearby red dwarf stars using the remotely-controlled telescope of the Southeastern Association for Research in Astronomy (SARA). Three-color observations are obtained with short, medium and long duration exposures to accurately measure the colors of stars. Observations are made with red (R), infrared (I), and calcium hydride (CaH) filters. This pilot project is designed to establish the photometric properties of stars detected in this type of survey and to perfect observation and data reduction techniques.
