First results from the Calan–Hertfordshire Extrasolar Planet Search : exoplanets and the discovery of an eccentric brown dwarf in the desert
(2009)
We report the discovery of a brown dwarf on an eccentric orbit and with a semimajor axis that places it in the brown dwarf desert region around the star HD 191760. The star has a spectral type of G3IV/V and a metallicity ...
Beyond the Iron Peak: r- and s-process Elemental Abundances in Stars with Planets
(2008)
We present elemental abundances of 118 stars (28 of which are known extrasolar planetary host stars) observed as part of the Anglo-Australian Planet Search. Abundances of O, Mg, Cr, Y, Zr, Ba, Nd, and Eu (along with ...
Precision Radial Velocity Spectrograph
(SPIE, 2008)
We present a conceptual design for a Precision Radial Velocity Spectrograph (PRVS) for the Gemini telescope. PRVS is a fibre fed high resolving power (R similar to 70,000 at 2.5 pixel sampling) cryogenic echelle spectrograph ...
Mining The Next Generation Of Surveys for Cool Star Science
(Astronomical Society of the Pacific, 2008)
A number of major new and near future survey facilities are set to have a large impact on cool star science. With increased sky coverage and sensitivity over a wide wavelength range and in the time domain, a variety of new ...
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey
(2008)
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 brings the total number of ...
