1 Sep 2011 | Abstract: | We report a nearby L7.5 dwarf discovered using the Preliminary Data Release
of the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All-Sky
Survey (2MASS). WISEP J180026.60+013453.1 has a motion of 0.42 arcsec/yr and an
estimated distance of 8.8 pm 1.0 pc. With this distance, it currently ranks as
the sixth closest known L dwarf, although a trigonometric parallax is needed to
confirm this distance. It was previously overlooked because it lies near the
Galactic Plane (b=12). As a relatively bright and nearby late L dwarf with
normal near-infrared colors, W1800+0134 will serve as a benchmark for studies
of cloud-related phenomena in cool substellar atmospheres. | Source: | arXiv, 1109.0054 | Services: | Forum | Review | PDF | Favorites |
