Population, the red dwarfs, searching for the most massive and least Include determining masses for the dominant members of the Galactic Understanding of the stars we see at night. Substellar objects to high precision using state-of-the-artĪstrometric and spectroscopic techniques, and thereby create a better The purpose of the MASSIF effort is to measure masses of stellar and MASSIF: Masses and Stellar Systems with Interferometry Mass is the single most important attribute of a star. That last a decade or more, much like our Sun's 11-year sunspot cycle. The second is a search for stellar cycles in red dwarfs Orbiting M dwarfs, in an effort to understand the orbitalĪrchitectures of companions to these small stars that account for 75% Search for stellar, brown dwarf, and Jovian planetary companions The effort hasĮvolved into two unique long-term studies of the behavior of redĭwarfs, otherwise known as M dwarfs. Within 25 parsecs, or 15% of all star systems so near. RECONS revealed for the first time more than 300 systems CTIOPI started under theĪuspices of the NOAO Surveys Program and continues via the SMARTSĬonsortium. Tololo Interamerican Observatory, located in the foothills of theĬhilean Andes, since 1999 to discover red and white dwarfs that lurk CTIOPI: Cerro Tololo Interamerican Observatory Parallax Investigation The RECONS Team has used the 0.9m telescope at the Cerro Multiplicity fraction of the nearby stars. Spectroscopy at both optical and infrared wavelengths, as well asĭeterminations of the luminosity function, mass function, and Spectroscopic techniques, or through companionship studies at smallĪnd large separations. New members are found via astrometric, photometric, and Years) and to characterize all stars and planets within that distance Members of the sample of stars within 25 parsecs (about 80 light The projects described below are all associated The nature of the Sun's nearest stellar neighbors, both individuallyĪnd as a population.
