Distance ĭistance of WISE J2030+0749 was estimated by Bihain et al. JAstronomy & Astrophysics received the discovery paper, which was accepted for publication 10 July 2013. carried out follow up observations of WISE J2030+0749 with near-Infrared spectrograph LUCI 1 on LBT. Three objects among about ten candidates, including WISE J2030+0749, were selected for spectroscopic follow up with Large Binocular Telescope (LBT). selected sources with colours typical for T dwarfs from WISE All-Sky source catalogue and checked them for high proper motion using older surveys: 2MASS, DENIS, SDSS, SSS, DSS and UKIDSS. (2013) brown dwarfs is 87, all are of T-type. The total number of announced in Mace et al. ![]() The discovery paper was submitted to The Astrophysical Journal Supplement, accepted for publication on 2013 January 15 and published in March, 2013. ![]() SeptemWISE J2030+0749 was observed using SpeX at Infrared Telescope Facility (IRTF). selected T-type brown dwarf candidates from WISE All-Sky source catalogue and carried out follow up observations using a variety of telescopes. History of observations ĭiscovery of WISE J2030+0749 was announced in 2013 by Mace et al. WISE J2030+0749 is a nearby brown dwarf of spectral type T1.5, in constellat,ion Delphinus, approximately 10.5 pc (34.2 ly) from Earth. ![]()
