    • 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 ...
