Benchmark ultra-cool dwarfs in widely separated binary systems (2009)
Zhang, Z. H., Pinfield, D. J., Day-Jones, A. C., Burningham, B., Jones, H. R. A.
Ultra-cool dwarfs as wide companions to subgiants, giants, white dwarfs and main sequence stars can be very good benchmark objects, for which we can infer physical properties with minimal reference...
Zhang, Z. H., Pokorny, R. S., Jones, H. R. A., Pinfield, D. J., Chen, P. S., Han, Z., ...
Aims. We try to identify ultra-cool dwarfs from the seventh Data Release of the Sloan Digital Sky Survey (SDSS DR7) with SDSS i-z and r-z colors. We also obtain proper motion data from SDSS, 2MASS,...
The Physical Properties of Four ~600K T Dwarfs (2009)
Leggett, S. K., Cushing, M. C., Saumon, D., Marley, M. S., Roellig, T. L., Warren, S. J., ...
We present Spitzer 7.6-14.5um spectra of ULAS J003402.77-005206.7 and ULAS J133553.45+113005.2, two T9 dwarfs with the latest spectral types currently known. We fit synthetic spectra and photometry...

Identifying nearby field T dwarfs in the UKIDSS Galactic Clusters Survey (2008)
Lodieu, N., Burningham, B., Hambly, N. C., Pinfield, D. J.
We present the discovery of two new late-T dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data Release 2 (DR2). These T dwarfs are nearby old T dwarfs...

Optical and near-infrared (NIR) spectra are presented for ULAS J131911.29+095951.4 (hereafter ULAS J1319+0950), a new redshift z = 6.127 +/- 0.004 quasar discovered in the Third Data Release (DR3) of...
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey (2008)
Pinfield, D. J., Burningham, B., Tamura, M., Leggett, S. K., Lodieu, N., Lucas, P. W., ...
We present the discovery of fifteen new T2.5-T7.5 dwarfs (with estimated distances between ~24-93pc, identified in the first three main data releases of the UKIRT Infrared Deep Sky Survey. This...
A search for southern ultracool dwarfs and wide binary systems in young moving groups (2008)
Clarke, J. R. A., Pinfeld, D. J., Burningham, B., Galvez, M. C., Deacon, N. R., Jones, H. R. A., ...
We associate 135 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups using photometric and astrometric selection techniques. Of these objects, three...
