    • Effective temperatures, rotational velocities, microturbulent velocities and abundances in the atmospheres of the Sun, HD1835 and HD10700 

      Pavlenko, Ya.; Jenkins, J.; Jones, H.R.A.; Ivanyuk, O.; Pinfield, D.J. (2012)
      We describe our procedure to determine effective temperatures, rotational velocities, microturbulent velocities, and chemical abundances in the atmospheres of Sun-like stars. We use independent determinations of iron ...

    • The first planet detected in the WTS : an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM] 

      Cappetta, M.; Saglia, R.P.; Birkby, J. L.; Koppenhoefer, J.; Pinfield, D.J.; Hodgkin, S.T.; Cruz, P.; Kovacs, G.; Sipocz, B.; Barrado, D.; Nefs, B.; Pavlenko, Y. V.; Fossati, L.; Burgo, C. del; Martin, E. L.; Snellen, I.; Barnes, J.; Campbell, D. A.; Catalan, S.; Galvez-Ortiz, M. C.; Goulding, N.; Haswell, C.; Ivanyuk, O.; Jones, H.R.A.; Kuznetsov, M.; Lodieu, N.; Marocco, F.; Mislis, D.; Murgas, F.; Napiwotzki, R.; Palle, E.; Pollacco, D.; Baro, L. Sarro; Solano, E.; Steele, P.; Stoev, H.; Tata, R.; Zendejas, J. (2014-11-11)
      We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in August 2007. Light curves comprising ...

    • A hot Uranus orbiting the super metal-rich star 77338 and the metallicity-mass connection 

      Jenkins, J. S.; Jones, H.R.A.; Tuomi, M.; Murgas, F.; Hoyer, S.; Jones, M. I.; Barnes, J. R.; Pavlenko, Y. V.; Ivanyuk, O.; Rojo, P.; Jordan, A.; Day-Jones, A. C.; Ruiz, M. T.; Pinfield, D.J. (2013-04-01)
      We announce the discovery of a low-mass planet orbiting the super metal-rich K0V star HD 77338 as part of our ongoing Calan-Hertfordshire Extrasolar Planet Search. The best-fit planet solution has an orbital period of ...

    • New Planetary Systems from the Calan-Hertfordshire Extrasolar Planet Search and the Core Accretion Mass Limit 

      Jenkins, J. S.; Jones, Hugh; Tuomi, Mikko; Diaz, M.; Cordero, J. P.; Aguayo, A.; Pantoja, B.; Arriagada, P.; Mahu, R.; Brahm, R.; Rojo, P.; Soto, M. G.; Ivanyuk, O.; Becerra Yoma, N.; Day-Jones, A. C.; Ruiz, M. T.; Pavlenko, Y. V.; Barnes, J. R.; Murgas, F.; Pinfield, David; Jones, M. I.; Lopez-Morales, M.; Shectman, S.; Butler, R. P.; Minniti, D. (2017-04-01)
      We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as part of the Calan–Hertfordshire Extrasolar ...

    • Two super-earths orbiting the solar analog HD 41248 on the edge of a 7 : 5 mean motion resonance 

      Jenkins, J. S.; Tuomi, Mikko; Brasser, R.; Ivanyuk, O.; Murgas, F. (2013-07-01)
      There are a growing number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances (MMRs). These systems are generally in first-order resonances and ...
