    • 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 ...
    • Erratum: “Search for Nearby Earth Analogs. II. Detection of Five New Planets, Eight Planet Candidates, and ... 
      Feng, Fabo; Butler, R. Paul; Shectman, Stephen A.; Crane, Jeffrey D.; Vogt, Steve; Chambers, John; Jones, Hugh R. A.; Wang, Sharon Xuesong; Teske, Johanna K.; Burt, Jennifer; Díaz, Matías R.; Thompson, Ian B. (IOP Publishing, 2020)
    • 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 ...

      Feng, Fabo; Butler, R. Paul; Shectman, Stephen A.; Crane, Jeffrey D.; Vogt, Steve; Chambers, John; Jones, Hugh R. A.; Wang, Sharon Xuesong; Teske, Johanna K.; Burt, Jenn; Díaz, Matías R.; Thompson, Ian B. (IOP Publishing, 2020)
      Zechmeister et al. surveyed 38 nearby M dwarfs from 2000 to 2007 March with VLT2 and the Ultraviolet and Visual Echelle Spectrograph (UVES) spectrometer. These data have recently been reanalyzed, yielding a significant ...
    • The Magellan PFS planet search program: radial velocity and stellar abundance analyses of the 360 au, ... 
      Teske, Johanna K.; Shectman, Stephen A.; Vogt, Steve S.; Díaz, Matías; Butler, R. Paul; Crane, Jeffrey D.; Thompson, Ian B.; Arriagada, Pamela (2016)
      We present a new precision radial velocity (RV) data set that reveals multiple planets orbiting the stars in the similar to 360 au, G2+G2 "twin" binary HD 133131AB. Our six years of high-resolution echelle observations ...
    • 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 ...
    • TOI-150: A Transiting Hot Jupiter in the TESS Southern CVZ 
      Cañas, Caleb I.; Stefansson, Gudmundur; Monson, Andrew J.; Teske, Johanna K.; Bender, Chad F.; Mahadevan, Suvrath; Aerts, Conny; Beaton, Rachael L.; Butler, R. Paul; Covey, Kevin R.; Crane, Jeffrey D.; De Lee, Nathan; Díaz, Matías R.; Fleming, Scott W.; García Hernández, D. A.; Hearty, Fred R.; Kollmeier, Juna A.; Majewski, Steven R.; Nitschelm, Christian; Schneider, Donald P.; Shectman, Stephen A.; Stassun, Keivan G.; Tkachenko, Andrew; Wang, Sharon X.; Wang, Songhu; Wilson, John C.; Wilson, Robert F. (IOP Publishing, 2019)
      We report the detection of a hot Jupiter (M-p = 1.75(-0.17)(+0.14) M-J, R-p = 1.38 +/- 0.04R(J)) orbiting a middle-aged star (log g = 4.152(-0.043)(+0.030)) in the Transiting Exoplanet Survey Satellite (TESS) southern ...
