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 ...
A metal-biased planet search
(American Institute of Physics (AIP), 2009)
We have begun a metal-rich planet search project using the HARPS instrument in La Silla, Chile to target planets with a high potential to transit their host star and add to the number of bright benchmark transiting planets. ...
Rotational velocities for M dwarfs
(2009)
We present spectroscopic rotation velocities (v sin i) for 56 M dwarf stars using high-resolution Hobby-Eberly Telescope High Resolution Spectrograph red spectroscopy. In addition, we have also determined photometric ...
Discovery of the First Very Wide WD LD Binary System
(Astronomical Society of the Pacific, 2007)
We report on our large scale search of 2MASS and SuperCOS- MOS in the southern hemisphere for very widely separated white dwarf / L-dwarf binary systems and present our findings, including eight widely separated can- didate ...
Near infrared spectroscopic search for the close orbiting planet HD 75289b
(2007)
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 ¹m- 2.19 ¹m using the Phoenix spectrograph ...
An activity catalogue of southern stars
(2006)
We have acquired high-resolution echelle spectra of 225 F6-M5 type stars in the southern hemisphere. The stars are targets or candidates to be targets for the Anglo- Australian Planet Search. CaII HK line cores were used ...
