    • Masses, oxygen, and carbon abundances in CHEPS dwarf stars 
      Pavlenko, Y. V.; Kaminsky, B. M.; Jenkins, James Stewart; Ivanyuk, O. M.; Jones, H.R.A.; Lyubchik, Y. P. (EDP Sciences, 2019)
      Context. We report the results from the determination of stellar masses, carbon, and oxygen abundances in the atmospheres of 107 stars from the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) programme. Our stars are ...
    • Precision radial velocities of 15 M5–M9 dwarfs 
      Barnes, J. R.; Jenkins, James Stewart; Jones, H.R.A.; Jeffers, S. V.; Rojo Rubke, Patricio; Arriagada, P.; Jordán, A.; Minniti, D.; Tuomi, M.; Pinfield, D. J.; Anglada Escudé, Guillem (Royal Astronomical Society, 2014-02-20)
      We present radial velocity measurements of a sample of M5V–M9V stars from our Red-Optical Planet Survey, operating at 0.652–1.025 µm. Radial velocities for 15 stars, with rms precision down to 2.5 m s−1 over a week-long ...
