    • 3D Selection of 167 Substellar Companions to Nearby Stars 

      Feng, Fabo; Butler, R. Paul; Vogt, Steven S.; Clement, Matthew S.; Tinney, C. G.; Cui, Kaiming; Aizawa, Masataka; Jones, Hugh R. A.; Bailey, J.; Burt, Jennifer; Carter, B. D.; Crane, Jeffrey D.; Dotti, Francesco Flammini; Holden, Bradford; Ma, Bo; Ogihara, Masahiro; Oppenheimer, Rebecca; O’Toole, S. J.; Shectman, Stephen A.; Wittenmyer, Robert A.; Wang, Sharon X.; Wright, D. J.; Xuan, Yifan (2022-08-26)
      We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in previous work. We find 914 radial velocity signals ...

    • The Anglo-Australian Planet Search XXIV: The Frequency of Jupiter Analogs 

      Wittenmyer, Robert A.; Butler, R. Paul; Tinney, C. G.; Horner, Jonathan; Carter, B. D.; Wright, D. J.; Jones, Hugh; Bailey, J.; O'Toole, Simon J. (2016-03-01)
      We present updated simulations of the detectability of Jupiter analogs by the 17-year Anglo-Australian Planet Search. The occurrence rate of Jupiter-like planets that have remained near their formation locations beyond the ...

    • Cool Jupiters greatly outnumber their toasty siblings : Occurrence rates from the Anglo-Australian Planet Search 

      Wittenmyer, Robert A.; Wang, Songhu; Horner, Jonathan; Butler, R. P.; Tinney, C. G.; Carter, B. D.; Wright, D. J.; Jones, H. R. A.; Bailey, J.; O'Toole, S. J.; Johns, Daniel (2020-02-01)
      Our understanding of planetary systems different to our own has grown dramatically in the past 30 yr. However, our efforts to ascertain the degree to which the Solar system is abnormal or unique have been hindered by the ...

    • Signals embedded in the radial velocity noise: Periodic variations in the tau Ceti velocities 

      Tuomi, Mikko; Jones, H.R.A.; Jenkins, James Stewart; Tinney, C.G.; Butler, R.P.; Vogt, Steven S.; Barnes, John; Wittenmyer, Robert A.; O'Toole, S.; Horner, J.; Bailey, J.; Carter, B.D.; Wright, D. J.; Salter, G. S.; Pinfield, D.J. (2013-03)
      Context. The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a combination of instrument precision, lack of data, and “jitter”. Jitter is a general term ...
