    • The 2:1 resonant exoplanetary system orbiting HD 73526 

      Tinney, C.G.; Butler, R.P.; Marcy, G.W.; Jones, H.R.A.; Laughlin, G.; Carter, B.D.; Bailey, J.; O'Toole, S. (2006)
      We report the detection of a second exoplanet orbiting the G6 V dwarf HD 73526. This second planet has an orbital period of 377 days, putting it in a 2:1 resonance with the previously known exoplanet, the orbital period ...

    • A long-period planet orbiting a nearby Sun-like star 

      Jones, H.R.A.; Butler, R.P.; Tinney, C.G.; O'Toole, S.; Wittenmyer, R.; Henry, G.W.; Meschiari, S.; Vogt, S.; Rivera, E.; Laughlin, G.; Carter, B.D.; Bailey, J.; Jenkins, J.S. (2010)
      The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from the Anglo-Australian Telescope (AAT). ...

    • A Neptune-mass Planet Orbiting the Nearby G Dwarf HD 16417 

      O'Toole, S.; Tinney, C.G.; Butler, R.P.; Jones, H.R.A.; Bailey, J.; Carter, B.D.; Vogt, S.; Laughlin, G.; Rivera, E. (2009)
      Precision Doppler measurements from an intensive 48 night "Rocky Planet Search" observing campaign on the Anglo-Australian Telescope (AAT) have revealed the presence of a low-mass exoplanet orbiting the G1 dwarf HD 16417. ...

    • A super-earth and two Neptunes orbiting the nearby sun-like star 61 Virginis 

      Vogt, S.; Wittenmyer, R.; Butler, R.P.; O'Toole, S.; Henry, G.W.; Rivera, E.; Meschiari, S.; Laughlin, G.; Tinney, C.G.; Jones, H.R.A.; Bailey, J.; Carter, B.D.; Batygin, K. (2010)
      We present precision radial velocity data that reveal a multiple exoplanet system orbiting the bright nearby G5V star 61 Virginis. Our 4.6 years of combined Keck/HIRES and Anglo-Australian Telescope precision radial ...
