    • A hot Saturn on an eccentric orbit around the giant star K2-132 
      Jones, M. I.; Brahm, R.; Espinoza N., Arturo; Jordán, A.; Rojas, F.; Rabus, M.; Drass, H.; Zapata, A.; Soto, M. G.; Jenkins, James Stewart; Vuckovic, M.; Ciceri, S.; Sarkis, P. (EDP Sciences, 2018)
      Although the majority of radial velocity detected planets have been found orbiting solar-type stars, a fraction of them have been discovered around giant stars. These planetary systems have revealed different orbital ...

    • 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 ...
    • K2-161b: A low-density super-neptune on an eccentric orbit 
      Brahm, R.; Espinoza N., Arturo; Rabus, M.; Jordán, A.; Díaz, M. R.; Rojas, F.; Vučković, M.; Zapata, A.; Cortés, C.; Drass, H.; Jenkins, James Stewart; Lachaume, R.; Pantoja, B.; Sarkis, P.; Soto, M. G.; Vasquez, S.; Henning, Th; Jones, M. I. (Oxford University Press, 2019)
      © 2018 The Author(s).We report the discovery of K2-161b, which was first identified as a planetary candidate from Kepler K2 photometry of Campaign 14, and whose planetary nature and orbital parameters were then confirmed ...
    • K2-232 b: a transiting warm Saturn on an eccentric P = 11.2 d orbit around a V = 9.9 star 
      Brahm, R.; Espinoza, N.; Jordan, A.; Rojas, F.; Sarkis, P.; Díaz, M. R; Rabus, M.; Drass, H.; Lachaume, R.; Soto, M. G.; Jenkins, James Stewart; Jones, M. I.; Henning, Thomas; Pantoja, B.; Vuckovic, M. (Oxford University Press, 2018-06)
      We report the discovery of K2-232 b using photometric data of the Kepler K2 satellite coupled with ground-based spectroscopic observations. K2-232 b has a mass of M-P = 0.397 +/- 0.037 M-J, a radius of R-P = 1.00 +/- 0.020 ...
    • K2-237 b and K2-238 b: Discovery and characterization of two new transiting hot Jupiters from K2 
      Soto, M.; Díaz, M.; Jenkins, James Stewart; Rojas, F.; Espinoza, N.; Brahm, R.; Drass, H.; Jones, M.; Rabus, M.; Hartman, J.; Sarkis, P.; Jordán, A.; Lachaume, R.; Pantoja, B.; Vučković, M.; Ciardi, D.; Crossfield, I.; Dressing, C.; Gonzales, E.; Hirsch, L. (Oxford University Press, 2018)
      We report the discovery of two hot Jupiters orbiting the stars K2-237 and K2-238. We used photometric data from Campaigns 11 and 12 of the Kepler K2 mission and radial velocity data obtained using the HARPS, FEROS, and ...
    • 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 ...
    • A planetary system and a highly eccentric brown dwarf around the giant stars HIP 67851 and HIP 97233 
      Jones, M. I.; Jenkins, James Stewart; Rojo Rubke, Patricio; Melo, C.; Bluhm, P. (EDP Sciences, 2015)
      Context. So far more than 60 substellar companions have been discovered around giant stars. These systems present physical and orbital properties that contrast with those detected orbiting less evolved stars. Aims. We are ...
    • SAFARI - I. A SPHERE discovery of a super metal-rich M-dwarf companion to the star HD 86006 
      Pantoja, B.; Jenkins, James Stewart; Girard, J.; Vigan, A.; Salter, G.; Jones, M. (Oxford University Press, 2018)
      We report the direct detection of a fully convective, early-to-midM-dwarf companion orbiting the star HD 86006, using ESO-SPHERE during Science Verification as part of the SAFARI program. HARPS+CORALIE radial velocity ...
