    • 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 ...

    • A planetary system around the nearby M dwarf GJ 667C with at least one super-earth in its habitable zone 

      Anglada-Escude, Guillem; Arriagada, Pamela; Vogt, Steven S.; Rivera, Eugenio J.; Butler, R. Paul; Crane, Jeffrey D.; Shectman, Stephen A.; Thompson, Ian B.; Minniti, Dante; Haghighipour, Nader; Carter, Brad D.; Tinney, C.G.; Wittenmyer, Robert A.; Bailey, Jeremy A.; O'Toole, Simon J.; Jones, H.R.A.; Jenkins, J.S. (2012-05-20)
      We re-analyze 4 years of HARPS spectra of the nearby M1.5 dwarf GJ 667C available through the European Southern Observatory public archive. The new radial velocity (RV) measurements were obtained using a new data analysis ...

    • Search for nearby Earth analogs I. 15 planet candidates found in PFS data 

      Feng, Fabo; Crane, Jeffrey D.; Wang, Sharon Xuesong; Teske, Johanna K.; Shectman, Stephen A.; Díaz, Matías R.; Thompson, Ian B.; Jones, Hugh R. A.; Butler, R. Paul (2019-06-17)
      The radial velocity (RV) method plays a major role in the discovery of nearby exoplanets. To efficiently find planet candidates from the data obtained in high-precision RV surveys, we apply a signal diagnostic framework ...

    • Search for Nearby Earth Analogs. II. detection of five new planets, eight planet candidates, and confirmation of three planets around nine nearby M dwarfs 

      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; Diaz, Matias R.; Thompson, Ian B. (2020-01-08)
      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 ...
