The UKIRT Wide Field Camera ZYJHK Photometric System: Calibration from 2MASS
S. T. Hodgkin, M. J. Irwin, P. C. Hewett +1
In this paper we describe the photometric calibration of data taken with the near-infrared Wide Field Camera (WFCAM) on the United Kingdom Infrared Telescope (UKIRT). The broadband…
Eight new T4.5-T7.5 dwarfs discovered in the UKIDSS Large Area Survey Data Release 1
N. Lodieu, D. J. Pinfield, S. K. Leggett +4
We present eight new T4.5-T7.5 dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) Data Release 1 (DR1). In addition we have recovered the T4.5…
The UKIRT Infrared Deep Sky Survey ZYJHK Photometric System: Passbands and Synthetic Colours
Paul C. Hewett, Stephen J. Warren, Sandy K. Leggett +1
The UKIRT Infrared Deep Sky Survey is a set of five surveys of complementary combinations of area, depth, and Galactic latitude, which began in 2005 May. The surveys use the UKIRT…
Discovery of Five Very Low Mass Close Binaries, Resolved in the Visible with Lucky Imaging
N. M. Law, S. T. Hodgkin, C. D. Mackay
We survey a sample of 32 M5-M8 stars with distance < 40pc for companions with separations between 0.1 arcsec and 1.5 arcsec and with Delta m_i <5. We find five new VLM binaries wit…
On the properties of young multiple stars
E. J. Delgado-Donate, C. J. Clarke, M. R. Bate +1
Abridged/ We present numerical results on the properties of young binary and multiple stellar systems. Our analysis is based on a series of SPH + Nbody simulations of the fragmenta…
The European Large Area ISO Survey (ELAIS): Optical Identifications of 15 micron and 1.4 GHz sources in N1 and N2
E. A. Gonzalez-Solares, I. Perez-Fournon, M. Rowan-Robinson +9
We present the optical identification of mid-IR and radio sources detected in the European Large Area ISO Survey (ELAIS) areas N1 and N2. Using the r' band optical data from the Wi…
