A very cool brown dwarf in UKIDSS DR1
S. J. Warren, D. J. Mortlock, S. K. Leggett +21
(abridged) We report the discovery of a very cool brown dwarf, ULAS J003402.77-005206.7 (ULAS J0034-00), identified in UKIDSS DR1. We provide optical, near-infrared, and mid-infrar…
Trigonometric parallaxes of high velocity halo white dwarf candidates
C. Ducourant, R. Teixeira, N. C. Hambly +5
The status of 38 halo white dwarf candidates identified by Oppenheimer et al. (2001) has been intensively discussed by various authors. In analyses undertaken to date, trigonometri…
Southern Infrared Proper Motion Survey II: A sample of low mass stars with μ> 0.1''/yr
N. R. Deacon, N. C. Hambly
We present details of the second part of the Southern Infrared Proper Motion Survey (SIPS). Here accurate relative astrometry allows us to reduce the minimum proper motion to 0.1 a…
New members in the Upper Sco association from the UKIDSS Early Data Release
N. Lodieu, N. C. Hambly, R. F. Jameson
We present the results of a 9.3 square degree infrared (ZYJHK) survey in the Upper Scorpius association extracted from the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Cluster…
The UKIRT Infrared Deep Sky Survey Early Data Release
S. Dye, S. J. Warren, N. C. Hambly +11
This paper defines the UKIRT Infrared Deep Sky Survey (UKIDSS) Early Data Release (EDR). UKIDSS is a set of five large near-infra-red surveys defined by Lawrence et al. (2006), bei…
Proper motion surveys of the young open clusters Alpha Persei and the Pleiades
N. R. Deacon, N. C. Hambly
In this paper we present surveys of two open clusters using photometry and accurate astrometry from the SuperCOSMOS microdensitometer. These use plates taken by the Palomar Oschin…
