HD 179949b: A Close Orbiting Extrasolar Giant Planet with a stratosphere?
J. R. Barnes, Travis S. Barman, H. R. A. Jones +4
We have carried out a search for the 2.14 micron spectroscopic signature of the close orbiting extrasolar giant planet, HD 179949b. High cadence time series spectra were obtained w…
Exploring the substellar temperature regime down to ~550K
Ben Burningham, D. J. Pinfield, S. K. Leggett +15
We report the discovery of three very late T dwarfs in the UKIRT Infrared Deep Sky Survey (UKIDSS) Third Data Release: ULAS J101721.40+011817.9 (ULAS1017), ULAS J123828.51+095351.3…
Metallicities & Activities of Southern Stars
J. S. Jenkins, H. R. A. Jones, Y. Pavlenko +3
We present the results from high-resolution spectroscopic measurements to determine metallicities and activities of bright stars in the southern hemisphere. We have measured the ir…
Limits on the 2.2 microns contrast ratio of the close orbiting planet HD 189733b
J. R. Barnes, Travis S. Barman, L. Prato +5
We obtained 238 spectra of the close orbiting extrasolar giant planet HD 189733b with resolution R ~ 15,000 during one night of observations with the near infrared spectrograph, NI…
Near infrared spectroscopic search for the close orbiting planet HD 75289b
J. R. Barnes, C. J. Leigh, H. R. A. Jones +4
We present a search for the near infrared spectroscopic signature of the close orbiting extrasolar giant planet HD 75289b. We obtained ~230 spectra in the wavelength range 2.18 - 2…
New, nearby bright southern ultracool dwarfs
T. R. Kendall, H. R. A. Jones, D. J. Pinfield +5
We report the discovery of twenty-one hitherto unknown bright southern ultracool dwarfs with spectral types in the range M7 to L5.5, together with new observations of a further thr…
