Abstract

We present 8-15 μm spectra of ULAS J003402.77-005206.7, an extremely late-type T dwarf. We fit synthetic spectra to the near-through mid-infrared energy distribution of this dwarf, as well as to the near-infrared spectra of two similar dwarfs, ULAS J133553.45+113005.2 and CFBDS J005910.82-011401.3. The fit to ULAS J133553.45+113005.2 is constrained using midinfrared photometry. We derive effective temperatures of 550-600 K for all three of these T9 dwarfs; ULAS J003402.77-005206.7 appears to be the least massive (5-30 M_Jup), and CFBDS J005910.82-011401.3 the most massive (30-50 M_Jup).
