    • GJ 832c: a super-earth in the habitable zone 
      Wittenmyer, Robert A.; Tuomi, Mikko; Butler, R. P.; Jones, H. R.; Anglada Escudé, Guillem; Horner, Jonathan; Tinney, C. G.; Marshall, J. P.; Carter, B. D.; Bailey, J.; Salter, G. S.; O’Toole, S. J.; Wright, D.; Crane, J. D.; Schectman, S. A.; Arriagada, P.; Thompson, I.; Minniti, D.; Jenkins, James Stewart; Diaz, M. (The American Astronomical Society., 2014)
      We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an Mdwarf previously known to host a Jupiter analog in a nearly circular 9.4 yr orbit. The combination of ...
    • The Pan-Pacific Planet Search. IV. Two super-Jupiters in a 3:5 resonance orbiting the giant star HD 33844 
      Wittenmyer, Robert; Johnson, John; Butler, R.; Horner, Jonathan; Wang, Liang; Robertson, Paul; Jones, M.; Jenkins, James Stewart; Brahm, R.; Tinney, C.; Mengel, M.; Clark, J. (IOP PUBLISHING, 2016)
      We report the discovery of two giant planets orbiting the K giant HD 33844 based on radial velocity data from three independent campaigns. The planets move on nearly circular orbits with semimajor axes a(b) = 1.60 +/- 0.02 ...
    • The Pan-Pacific Planet Search. VII. the Most Eccentric Planet Orbiting a Giant Star 
      Wittenmyer, Robert A.; Jones, M. I.; Horner, Jonathan; Kane, Stephen R.; Marshall, J. P.; Mustill, A. J.; Jenkins, James Stewart; Pena Rojas, P. A.; Zhao, Jinglin; Villaver, Eva; Butler, R. P.; Clark, Jake (IOP Publishing, 2017)
      Radial velocity observations from three instruments reveal the presence of a 4 M Jup planet candidate orbiting the K giant HD 76920. HD 76920b has an orbital eccentricity of 0.856 ±0.009, making it the most eccentric planet ...
    • TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet

G; Udry, Stephane; Villasenor, Jesus Noel; Vines, Jose; Wang, Sharon X.; Weiss, Lauren M.; West, Richard G.; Wheatley, Peter J.; Wright, Duncan J.; Zhang, Hui; Zohrabi, F. (Oxford, 2021)
      We present the bright (V-mag = 9.12), multiplanet system TOI-431, characterized with photometry and radial velocities (RVs). We estimate the stellar rotation period to be 30.5 +/- 0.7 d using archival photometry and RVs. ...
