    • Benchmark cool companions : Ages and abundances for the PZ Tel system 

      Jenkins, J. S.; pavlenko, Yakiv; Ivanyuk, Oleksiy; Gallardo, Jose; jones, Matias; day-jones, Avril; Jones, H.R.A.; Ruiz, Maria-Teresa; Pinfield, D.J.; Yakovina, Larissa (2012-03)
      We present new ages and abundance measurements for the pre-main sequence star PZ Tel. PZ Tel was recently found to host a young and low-mass companion. Using FEROS spectra we have measured atomic abundances (e.g. Fe and ...

    • Measuring ultracool properties from the UKIDSS Large Area Survey 

      Day-Jones, Avril; Marocco, F.; Pinfield, D.J.; Zhang, Zenghua; Burningham, B.; Deacon, Niall; Ruiz, Maria-Teresa; Gallardo, Jose; Jones, H.R.A.; Lucas, P.W.; Jenkins, James; Gomes, Joana; Folkes, Stuart; Clarke, James (EDP Sciences, 2013)
      We discuss the properties and of ultracool and brown dwarfs that can be measured from current large area surveys and how fundamental parameters, such as the mass function and formation history can be measured, describing ...

    • Status of the Calan-Hertfordshire Extrasolar Planet Search 

      Jenkins, James S.; Jones, H.R.A.; Rojo, Patricio; Tuomi, Mikko; Jones, Matias I.; Murgas, Felipe; Barnes, J.R.; Pavlenko, Yakiv; Ivanyuk, Oleksiy; Jordan, Andres; Day-Jones, Avril C.; Ruiz, Maria-Teresa; Pinfield, D.J. (EDP Sciences, 2013)
      In these proceedings we give a status update of the Calan-Hertfordshire Extrasolar Planet Search, an international collaboration led from Chile that aims to discover more planets around super metal-rich and Sun-like stars, ...
