WISE J2030+0749
WISE J2030+0749 is a nearby brown dwarf of spectral type T1.5, located in constellation Template:Constel at approximately 10.5 pc (34.2 ly) from Earth.[1]
History of observations
WISE J2030+0749 was discovered by Bihain et al. by selection of sources with colours typical for T dwarfs from WISE All-Sky source catalogue and checking them for high proper motion using older surveys: 2MASS, DENIS, SDSS, SSS, DSS and UKIDSS. Three objects among about ten candidates, including WISE J2030+0749, were selected for spectroscopic follow up with Large Binocular Telescope (LBT). November 8, 2012 Bihain et al. carried out follow up observations of WISE J2030+0749 with near-Infrared spectrograph LUCI 1 on LBT. June 25, 2013 Astronomy & Astrophysics received the discovery paper, which was accepted for publication 10 July 2013.[1]
Distance
Distance of WISE J2030+0749 was estimated by Bihain et al. using mean absolute magnitudes of single T1/T2 dwarfs, derived by Dupuy & Liu (2012) from trigonometric parallaxes:[2] 10.5 ± 2.6 pc (34.2 ± 8.5 ly).[1]
