    • The extremely red L dwarf ULAS J222711-004547-dominated by dust 

      Marocco, F.; Day-Jones, A. C.; Lucas, P.W.; Jones, H.R.A.; Smart, R.L.; Zhang, Z. H.; Gomes, J. I.; Burningham, B.; Pinfield, D.J.; Raddi, R.; Smith, Leigh (2014-03)
      We report the discovery of a peculiar L dwarf from the United Kingdom Infrared Deep Sky Survey Large Area Survey, ULAS J222711-004547. The very red infrared photometry (MKO J-K = 2.79 +/- 0.06, WISEW1-W2 = 0.65 +/- 0.05) ...

    • A large spectroscopic sample of L and T dwarfs from UKIDSS LAS : peculiar objects, binaries, and space density 

      Marocco, F.; Jones, H.R.A.; Day-Jones, A. C.; Pinfield, D.J.; Lucas, P.W.; Burningham, B.; Zhang, Z. H.; Smart, R.L.; Gomes, J. I.; Smith, L. (2015-06-01)
      We present the spectroscopic analysis of a large sample of late-M, L, and T dwarfs from UKIDSS. Using the YJHK photometry from ULAS and the red-optical photometry from SDSS we selected a sample of 262 brown dwarf candidates ...

    • Two new ultracool benchmark systems from WISE+2MASS 

      Gomes, J. I.; Pinfield, D.J.; Marocco, F.; Day-Jones, A. C.; Burningham, B.; Zhang, Z. H.; Jones, H.R.A.; van Spaandonk, L.; Weights, D. (2013-05)
      We have used the Two-Micron All-Sky Survey and the Wide-field Infrared Survey Explorer to look for ultracool dwarfs that are part of multiple systems containing main-sequence stars. We cross-matched L dwarf candidates from ...
