    • J-band variability of M dwarfs in the WFCAM Transit Survey 

      Goulding, N. T.; Barnes, J. R.; Pinfield, D.J.; Kovacs, G.; Birkby, J.; Hodgkin, S.; Catalan, S.; Sipocz, B.; Jones, H.R.A.; del Burgo, C.; Jeffers, S.V.; Nefs, S.; Galvez-Ortiz, M. -C.; Martin, E. L. (2012-12)
      We present an analysis of the photometric variability of M dwarfs in the Wide Field Camera (WFCAM) Transit Survey. Although periodic light-curve variability in low mass stars is generally dominated by photospheric star ...

    • Periodic variability of spotted M dwarfs in WTS 

      Goulding, N. T.; Barnes, J.R.; Pinfield, D.J.; del Burgo, C.; Kovacs, G.; Birkby, J.; Hodgkin, S.; Catalan, S.; Sipocz, B.; Jones, H.R.A.; Jeffers, S.V.; Nefs, S. (EDP Sciences, 2013)
      We present an analysis of the photometric variability of M dwarfs in the WFCAM Transit Survey, selected from spectral types inferred by their WTS and SDSS colours, with periods detected using a Lomb-Scargle Periodogram ...

    • Praesepe - two merging clusters? 

      Holland, K.; Jameson, Richard F.; Hodgkin, S.; Davies, M.B.; Pinfield, D.J. (2000-12-11)
      A membership catalogue for Praesepe was compiled and split into four mass bins. A contour plot indicates the presence of a subcluster some 3 pc from the centre of the cluster, of approximately 30 M-circle dot. A tidally ...

(2014-11-11)
      The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes ℓ = 30°–215° in the r, i, and Hα filters using the Wide Field Camera ...
