(IOP Publishing Ltd, 2017)
      We present a spectroscopic survey of high-redshift, luminous galaxies over four square degrees on the sky, aiming to build a large and homogeneous sample of Ly alpha emitters (LAEs) at z approximate to 5.7 and 6.5, and ...
    • A six planet system around the Star HD 34445

      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 ...
    • TESS Reveals a short-period sub-neptune sibling (HD 86226c) to a known long-period giant planet

      The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here, we present the detection and mass measurement of a small, short-period (≈4 days) transiting ...
    • 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
