Title: Characterizing M Dwarf Systems in the Stellar Neighborhood

Abstract: We propose to use the Differential Speckle Survey Instrument (DSSI) on the WIYN 3.5m to survey hundreds of the nearest red dwarfs to reveal companions. DSSI on WIYN is able to detect companions with separations as small as the Sun to Mercury for stars out to 25 pc. Here we focus on the nearest M dwarfs with WIYN to complement our efforts using Gemini-N and Gemini-S, where more distant stars in the sample will be observed to provide comparable resolution. The resulting portrait of single, binary, triple, and higher order multiple star systems will drive research on star formation processes for the dominant population of stars in the Galaxy, while individual measurements of companion locations and types will be used as benchmarks for decades. Ultimately, we will answer the basic questions of whether or not most stars are single or multiple, by how much the multiplicity changes with stellar mass, and which stars orbit one another in such configurations that make it difficult for the creation of planets.
