  • EC 10246-2707: a new eclipsing sdB + M dwarf binary⋆ 

    Barlow, B.N.; Kilkenny, David; Drechsel, H.; Dunlap, B.H. (OUP, 2013)
    We announce the discovery of a new eclipsing hot subdwarf B + M dwarf binary, EC 10246-2707, and present multi-colour photometric and spectroscopic observations of this system. Similar to other HW Vir-type binaries, the ...
  • The Edinburgh-Cape Blue Object Survey - III. Zone 2; galactic latitudes -30? > b > -40? 

    Kilkenny, David; Koen, Chris; Hambly, N.; MacGillivray, H.; Stobie, R. S.; O’Donoghue, D. (Oxford University Press, 2013)
    The Edinburgh–Cape Blue Object Survey seeks to identify point sources with an ultraviolet excess. Results for zone 2 of the survey are presented here, covering that part of the South Galactic Cap between 30◦ and 40◦ from ...
  • JL 82: a slowly pulsating hot subdwarf star in a close binary system 

    Koen, Chris (Oxford University Press, 2009)
    JL 82 is a known binary, consisting of an sdB star and a companion which is not directly observable in the optical. Photometric measurements reported in this paper show it to variable with both the binary period (∼0.75 ...
  • KPD 0629–0016, a slowly pulsating hot subdwarf star 

    Koen, Chris; Green, E.M. (Oxford University Press, 2007)
    The results of nine CCD photometric observing runs on KPD 0629–0016 are presented. During six of the runs measurements were obtained alternately through B and V filters. Four periodicities, for which there is good agreement ...
  • Two new pulsating hot subdwarf stars from the Edinburgh-Cape survey 

    Kilkenny, David; O'Donoghue, D.; Crause, L.; Engelbrecht, C.; Hambly, N.; MacGillivray, H. (Oxford University Press, 2009)
    We report the discovery of very rapid pulsations in two hot subdwarf stars from the Edinburgh- Cape blue object survey. The short periods, small amplitudes and multiperiodicity establish these stars as members of the ...
