A Search for Y Dwarf Companions to Nearby Stars and Brown Dwarfs
Abstract
We propose to obtain IRAC images of a large sample of nearby stars and brown dwarfs that we observed with IRAC during the first 3 years of the Spitzer mission. By combining the data at these two epochs, we will search for substellar companions through their common proper motions with the primaries. These observations will comprise the deepest survey to date for wide substellar companions to stars and brown dwarfs in the solar neighborhood, and should provide the best available opportunity for finding the brown dwarfs cooler than known T dwarfs, such as the as-of-yet-undiscovered Y dwarfs.
