We have monitored the position of the cool Y dwarf WISEPA J182831.08+265037.8 using a combination of ground- and space-based telescopes and have determined its distance to be 11.2{sup +1.3} {sub -1.0} pc. Its absolute H magnitude, M{sub H} = 22.21{sup +0.25} {sub -0.22} mag, suggests a mass in the range 0.5-20 M {sub Jup} for ages of 0.1-10 Gyr with an effective temperature in the range 250-400 K. The broad range in mass is due primarily to the unknown age of the object. Since the high… 
DISCOVERY OF A ∼250 K BROWN DWARF AT 2 pc FROM THE SUN*
Through a previous analysis of multi-epoch astrometry from the Wide-field Infrared Survey Explorer (WISE), I identified WISE J085510.83–071442.5 as a new high proper motion object. By combining
Near-Infrared Detection of WD 0806-661 B with the Hubble Space Telescope
WD 0806-661 B is one of the coldest known brown dwarfs (T {sub eff} = 300-345 K) based on previous mid-infrared photometry from the Spitzer Space Telescope. In addition, it is a benchmark for testing
WISE Y DWARFS AS PROBES OF THE BROWN DWARF-EXOPLANET CONNECTION
We have determined astrometric positions for 15 WISE-discovered late-type brown dwarfs (six T8-9 and nine Y dwarfs) using the Keck-II telescope, the Spitzer Space Telescope, and the Hubble Space
A New Parallax Measurement for the Coldest Known Brown Dwarf
WISE J085510.83-071442.5 was recently discovered as the coldest known brown dwarf based on four epochs of images from the Wide-field Infrared Survey Explorer and the Spitzer Space Telescope. We have
NEOWISE-R Observation of the Coolest Known Brown Dwarf
The Wide-field Infrared Survey Explorer (WISE) spacecraft has been reactivated as NEOWISE-R to characterize and search for near-Earth objects. The brown dwarf WISE J085510.83–071442.5 has now been
The Spectral Energy Distribution of the Coldest Known Brown Dwarf
WISE J085510.83-071442.5 (hereafter WISE 0855-0714) is the coldest known brown dwarf (~250 K) and the fourth closest known system to the Sun (2.2 pc). It has been previously detected only in the J
A search for millimeter emission from the coldest and closest brown dwarf with ALMA
Context. WISE J085510.83−071442.5 (W0855) is a unique object: with Teff ≈ 250 K it is the coldest known brown dwarf (BD), located at only ≈2.2 pc form the Sun. It is extremely faint, which makes any
Discovery of the Y1 Dwarf WISE J064723.23-623235.5
We present the discovery of a very cold, very low mass, nearby brown dwarf using data from the NASA Wide-field Infrared Survey Explorer (WISE). The object, WISE J064723.23–623235.5, has a very red
The Enigmatic Brown Dwarf WISEA J153429.75-104303.3 (a.k.a. “The Accident”)
Continued follow-up of WISEA J153429.75−104303.3, announced in Meisner et al., has proven it to have an unusual set of properties. New imaging data from Keck/MOSFIRE and HST/WFC3 shows that this
