    • A multiplanet system of super-Earths orbiting the brightest red dwarf star GJ 887 
      Jeffers, S. V.; Dreizier, S.; Barnes, J. R.; Haswell, C. A.; Nelson, R. P.; Rodríguez, E.; López González, M. J.; Morales, N.; Luque, R.; Zechmeister, M.; Vogt, S. S.; Jenkins, James Stewart; Palle, E.; Berdinas, Z. M.; Coleman, G.; Díaz, M. R.; Ribas, I.; Jones, H.R.A.; Butler, R. P.; Tinney, C. G.; Bailey, J.; Carter, B. D.; O'Toole, S.; Wittenmyer, R. A; Crane, J. D.; Feng, F.; Shectman, S. A.; Teske, J.; Reiners, A.; Amado, P. J.; Anglada Escude, G. (Amer Assoc Advancement Science, 2020)
      The closet exoplanets to the Sun provide opportunities for detailed characterization of planets outside the Solar System. We report the discovery, using radial velocity measurements, of a compact multiplanet system of ...
    • An eccentric companion at the edge of the brown dwarf desert orbiting the 2.4 M-circle dot giant star HIP 67537 
      Jones, M. I.; Brahm, R.; Wittenmyer, R. A.; Drass, H.; Jenkins, James Stewart; Melo, C. H. F.; Vos, J.; Rojo Rubke, Patricio (EDP Sciences, 2017)
      We report the discovery of a substellar companion around the giant star HIP 67537. Based on precision radial velocity measurements from CHIRON and FEROS high-resolution spectroscopic data, we derived the following orbital ...
    • Four new planets around giant stars and the mass-metallicity correlation of planet-hosting stars 
      Jones, M. L.; Jenkins, James Stewart; Brahm, R.; Wittenmyer, R. A.; Olivares, E. F.; Melo, C. H.; Rojo Rubke, Patricio; Jordan, A.; Drass, H.; Butler, R.; Wang, L. (EDP Sciences, 2016)
      Context. Exoplanet searches have revealed interesting correlations between the stellar properties and the occurrence rate of planets. In particular, different independent surveys have demonstrated that giant planets are ...
    • New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems 
      Bluhm, P.; Jones, M. I.; Vanzi, L.; Soto, M. G; Vos, J.; Wittenmyer, R. A.; Drass, H.; Jenkins, James Stewart; Olivares, F.; Mennickent, R. E.; Vuckovic, M.; Rojo, P.; Melo, C. H. F. (EDP Sciences, 2016)
      We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars ...
