Title: NESSI Survey of Potential Low-Mass Exoplanet Hosts
Abstract: We are carrying out a funded project to determine the stellar multiplicity rates of the lower main sequence at the brown dwarf-stellar transition point by conducting a comprehensive high spatial-resolution survey of the nearest 2,000 M-dwarfs. We are using the speckle cameras at WIYN, DCT, and Gemini-N on a range of apertures to determine multiplicity and fundamental stellar parameters for a volume-limited sample of these M-dwarf stars at unprecedented levels of accuracy, across the entire mass range for this class of stars. Previous investigations have overlooked the low-mass ($gtrsim$M4) range of the M sequence, due to both a lack of sensitivity and a lack of target inventory. Given the priority these targets will have for upcoming exoplanet studies of TESS and JWST - and the degree to which initially undetected multiplicity has affected Kepler results - a comprehensive survey of our nearby low-mass neighbors will produce a homogenous, complete catalog of fundamental utility. Our investigation leverages recent results from WISE and other nearby stars studies, to comprehensively expand and explore M-dwarf discovery space.
