Chromospheric activities and kinematics for solar type dwarfs and subgiants : analysis of the activity distribution and the AVR
Jenkins, J.S.; Murgas, F.; Rojo, P.; Jones, H.R.A.; Day-Jones, A.C.; Jones, M.I.; Clarke, J.R.A.; Ruiz, M.; Pinfield, D.J. (2011)Aims : In this work we present chromospheric activity indices, kinematics, radial-velocities, and rotational velocities for more than 850 FGK-type dwarfs and subgiant stars in the southern hemisphere and test how best to ... -
First results from the Calan–Hertfordshire Extrasolar Planet Search : exoplanets and the discovery of an eccentric brown dwarf in the desert
Jenkins, J.S.; Jones, H.R.A.; Gozdziewski, K.; Migaszewski, C.; Barnes, J.R.; Jones, M.I.; Rojo, P.; Pinfield, D.J.; Day-Jones, A.C.; Hoyer, S. (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
Jenkins, J.S.; Jones, H.R.A.; Barnes, J.R.; Pavlenko, Y.; Rojo, P.; Jones, M.I.; Day-Jones, A.C.; Pinfield, D.J. (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. ...
