We present 11 candidate late-type companions to nearby stars identified withdata from the Wide-field Infrared Survey Explorer (WISE) and the Two MicronAll-Sky Survey (2MASS). Eight of the candidates are likely to be companionsbased on their common proper motions with the primaries. The remaining threeobjects are rejected as companions, one of which is a free-floating T7 dwarf.Spectral types are available for five of the companions, which consist of M2V,M8.5V, L5, T8, and T8. Based on their photometry, the unclassified companionsare probably two mid-M dwarfs and one late-M/early-L dwarf. One of the T8companions, WISE J142320.84+011638.0, has already been reported by Pinfield andcoworkers. The other T8 companion, ULAS J095047.28+011734.3, was discovered byBurningham and coworkers through the United Kingdom Infrared Telescope InfraredDeep Sky Survey, but its companionship has not been previously recognized inthe literature. The L5 companion, 2MASS J17430860+8526594, is a new member of aclass of L dwarfs that exhibit unusually blue near-IR colors. Among thepossible mechanisms that have been previously proposed for the peculiar colorsof these L dwarfs, low metallicity does not appear to be a viable explanationfor 2MASS J17430860+8526594 since our spectrum of the primary suggests that itsmetallicity is not significantly subsolar.
