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. ...
Spectroscopic characterisation of close orbiting extrasolar giant planets
(American Institute of Physics (AIP), 2009)
A number of successful mid-infrared detections and studies of close orbiting extrasolar giant planetary atmospheres have been responsible for both driving and informing modelling efforts. Recent models have indicated that ...
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 ...
