Not-So-Bright BulbsNASA has just posted a press release on one of my recent results involving the very cold brown dwarf 2MASS J0939-2448. Based on observations from the Spitzer Space Telescope and ground-based astrometry, we find this source to be one of the coldest brown dwarfs known (600+/-35 K) and, because of its overluminosity, an (as-yet) unresolved double. The paper appears in today’s edition of Astrophysical Journal Letters.
