Abstract

A preliminary BVRIJHK analysis of the white dwarfs SSSPM J2231-7514 and SSSPM J2231-7515 is presented. Although both stars were reported to have T eff < 4000 K, the analysis here indicates T eff ≈ 4250 K for both SSSPM J2231-7514 and SSSPM J2231-7515. Given substantial scientific interest in the coolest extant degenerate stars, it is necessary to distinguish sub-4000 K objects from the bulk of cool white dwarfs. This analysis reiterates the importance of near-infrared observations in constraining the spectral energy distributions and effective temperatures of the coolest white dwarfs and briefly discusses their possible origins.
