    • A six planet system around the Star HD 34445 
      Vogt, Steven S.; Butler, R. Paul; Burt, Jennifer; Tuomi, Mikko; Laughlin, Gregory; Holden, Brad; Teske, Johanna K.; Shectman, Stephen A.; Crane, Jeffrey D.; Díaz, Matias; Thompson, Ian B.; Arriagada, Pamela; Keiser, Sandy (IOP Publishing Ltd., 2017)
      We present a new precision radial velocity (RV) data set that reveals a multi-planet system orbiting the G0V star HD 34445. Our 18-year span consists of 333 precision RV observations, 56 of which were previously published ...
    • A terrestrial planet candidate in a temperate orbit around Proxima Centauri 
      Anglada Escudé, Guillem; Amado, Pedro J.; Barnes, John; Berdinas, Zaira M.; Butler, R. Paul; Coleman, Gavin A. L.; Cueva, Ignacio de la; Dreizler, Stefan; Endl, Michael; Giesers, Benjamin; Jeffers, Sandra V.; Jenkins, James Stewart; Jones, Hugh R. A.; Kiraga, Marcin; Kuerster, Martin; López González, María J.; Marvin, Christopher J.; Morales, Nicolás; Morín, Julien; Nelson, Richard P.; Ortiz, José L.; Ofir, Aviv; Paardekooper, Sijme-Jam; Reiners, Ansgar; Rodríguez, Eloy; Rodríguez López, Cristina; Sarmiento, Luis F.; Strachan, John P.; Tsapras, Yiannis; Tuomi, Mikko; Zechmeister, Mathias (Nature, 2016)
      At a distance of 1.295 parsecs(1), the red dwarf Proxima Centauri (a Centauri C, GL 551, HIP 70890 or simply Proxima) is the Sun's closest stellar neighbour and one of the best-studied low-mass stars. It has an effective ...
    • Search for Nearby Earth Analogs .III. Detection of 10 New Planets, 3 Planet Candidates, and Confirmation ... 
      Feng, Fabo; Shectman, Stephen A.; Clement, Matthew S.; Vogt, Steven S.; Tuomi, Mikko; Teske, Johanna K.; Burt, Jennifer; Crane, Jeffrey D.; Holden, Bradford; Xuesong Wang, Sharon; Thompson, Ian B.; Díaz, Matías; Butler, R. Paul (IOP Publishing, 2020)
      Earth-sized planets in the habitable zones of M dwarfs are good candidates for the study of habitability and detection of biosignatures. To search for these planets, we analyze all available radial velocity data and apply ...
    • The Magellan/PFS Exoplanet Search: a 55-d period dense Neptune transiting the bright (V = 8.6) star HD 95338 
      Díaz, Matías R.; Jenkins, James; Feng, Fabo; Butler, R. Paul; Tuomi, Mikko; Shectman, Stephen A.; Thorngren, Daniel; Soto, Maritza G.; Vines, José I.; Teske, Johanna K.; Dragomir, Diana; Villanueva, Steven; Kane, Stephen R.; Berdiñas, Zaira M.; Crane, Jeffrey D.; Wang, Sharon; Arriagada, Pamela (Oxford University Press, 2020)
      We report the detection of a transiting, dense Neptune planet candidate orbiting the bright (V = 8.6) K0.5V star HD 95338. Detection of the 55-d periodic signal comes from the analysis of precision radial velocities from ...
    • The test case of HD 26965: difficulties disentangling weak doppler signals from stellar activity 
      Díaz, Matias R.; Jenkins, James Stewart; Tuomi, Mikko; Butler, R. Paul; Soto, Maritza G.; Teske, Johanna K.; Feng, Fabo; Shectman, Stephen A.; Arriagada, Pamela; Crane, Jeffrey D.; Thompson, Ian B.; Vogt, Steven S. (IOP Publishing Ltd, 2018)
      We report the discovery of a radial velocity signal that can be interpreted as a planetary-mass candidate orbiting the K dwarf HD 26965, with an orbital period of 42.364 +/- 0.015 days, or alternatively, as the presence ...
