    • The discovery of a very cool, very nearby brown dwarf in the Galactic plane 

      Lucas, P.W.; Tinney, C. G.; Burningham, B.; Leggett, S. K.; Pinfield, D.J.; Smart, Richard; Jones, H.R.A.; Marocco, F.; Barber, Robert J.; Yurchenko, Sergei N.; Tennyson, Jonathan; Ishii, Miki; Tamura, Motohide; Day-Jones, Avril C.; Adamson, Andrew; Allard, France; Homeier, Derek (2010)
      We report the discovery of a very cool, isolated brown dwarf, UGPS 0722−05, with the United Kingdom Infrared Telescope Deep Sky Survey (UKIDSS) Galactic Plane Survey. The near-infrared spectrum displays deeper H2O and CH4 ...
    • Multi-object and long-slit spectroscopy of very low mass brown dwarfs in the Orion Nebular Cluster 

      Suenaga, Takuya; Tamura, Motohide; Kuzuhara, Masayuki; Yanagisawa, Kenshi; Ishii, Miki; Lucas, P.W. (2014)
      We present the results of an H-and K-band multi-object and long-slit spectroscopic survey of substellar mass candidates in the outer regions of the Orion Nebula Cluster. The spectra were obtained using MOIRCS on the 8.2m ...
    • The Properties of the 500 K Dwarf UGPS J072227.51-054031.2, and a Study of the Far-Red Flux of Cold Brown Dwarfs 

      Leggett, S.; Saumon, D.; Marley, M.; Lodders, K.; Canty, J.; Lucas, P.W.; Smart, R.; Tinney, C.; Homeier, D.; Allard, F.; Burningham, B.; Day-Jones, A.; Fegley, B.; Ishii, Miki; Jones, H.R.A.; Marocco, F.; Pinfield, D.J.; Tamura, M. (2012-04-01)
      We present i and z photometry for 25 T dwarfs and one L dwarf. Combined with published photometry, the data show that the i - z, z - Y and z - J colors of T dwarfs are very red, and continue to increase through to the ...
