We present initial results from the Sloan Low-mass Wide Pairs of Kinematically Equivalent Stars (SLoWPoKES) survey, an ongoing effort to identify wide (a>100 AU), low-mass (mid-K-mid M) binary systems from the Sloan Digital Sky Survey (SDSS) photometric database. Bochanski et al. (2009, in prep.) have compiled a catalog of more than 33 million low-mass stars from the Sloan Digital Sky Survey, spread over a wide range of mass, spectral type, age, distance, metallicity, and activity. We searched for companions within 60'' of each star and used statistical matching of the proper motions, photometric distances, and reduced proper motions of each pair to remove the chance pairs. SLoWPoKES consists of ~2,000 red dwarf, subdwarf, and white dwarf-red dwarf pairs, as well as ~100 hierarchical triples. There are a significant number of systems at large distances (>500 pc) above the Galactic Plane which will allow us to explore the survivability of wide pairs over time as they interact with molecular clouds and other stars. Further work will exploit the coevality of these systems to examine and constrain the current empirical relations on activity and rotation of low-mass field dwarfs.
