Mapping the Local Dust Distribution with SDSS
Abstract
The narrow range of M dwarf g-r colors in SDSS photometry permits study of the three-dimensional dust distribution within 1 kpc. Distances to early M dwarfs are assigned using reddening-invariant photometric parallaxes and clouds are identified by persistent shifts in mean g-r colors along the line of sight. The observed reddening is compared against that predicted by Schlegel, Finkbeiner & Davis (1998).
