    • UBV(RI)C JHK observations of Hipparcos-selected nearby stars 

      Koen, Chris; Kilkenny, David; van Wyk, F.; Marang, F. (Oxford University Press, 2010)
      We present homogeneous, standardized UBV(RI)C photometry for over 700 nearby stars selected on the basis of Hipparcos parallaxes. Additionally, we list JHK photometry for about half of these stars, as well as L photometry ...

    • UBV(RI)C photometry of transiting planet hosting stars 

      Maxted, P.F.L.; Koen, Chris; Smalley, B. (Oxford University Press, 2011)
      We present new UBV(RI)C photometry of 22 stars that host transiting planets, 19 of which were discovered by the Wide Angle Search for Planets (WASP) survey. We use these data together with Two Micron All Sky Survey (2MASS) ...

    • What can be deduced from open cluster metallicity measurements? 

      Koen, Chris; Lombard, Fred (Oxford University Press, 2007)
      The dependence of [Fe/H] on galactocentric distance, distance from the galactic mid-plane and age is studied. Both ordinary least-squares and non-parametric regression in the form of a ‘generalized additive model’ are ...
