Abstract

We propose to obtain IRAC images of 328 stars, brown dwarfs, and white dwarfs in the solar neighborhood that have been observed previously with IRAC. By combining the data at these two epochs, we will search for wide (>100 AU) substellar companions through their common proper motions with the primaries. The detection limits will reach up to 100 times fainter than the faintest known T dwarfs. These observations will comprise the deepest survey for wide companions to nearby stars that is possible with any current or planned telescope, providing the best available opportunity for finding brown dwarfs cooler than known T dwarfs, such as the as-of-yet-undiscovered Y dwarfs.
