Spitzer Mid-Infrared Photometry of 500 - 750 K Brown Dwarfs
S. K. Leggett,Loic Albert,Étienne Artigau,Ben Burningham,X. Delfosse,Philippe Delorme,T. Forveille,Philip W. Lucas,Mark S. Marley,D. J. Pinfield,Céline Reylé,Didier Saumon,Richard L. Smart,Steve Warren +13 more
TL;DR: In this paper, the authors used the atmospheric and evolutionary models of Saumon & Marley to investigate the masses and ages of 13 very late-type T dwarfs, which have H-[4.5] > 3.2 and T_eff ~ 500 K to 750 K.
Journal ArticleDOI

Billions of stars: the near infrared view of the Plane with UKIDSS and VISTA
Philip W. Lucas,David Samuel +1 more
TL;DR: In this paper, the UKIDSS Galactic Plane Survey (GPS) is surveying the northern and equatorial plane in the J, H and K bands, and the authors report initial results from searches for new clusters and star formation regions.
