    • Pulsations and eclipse-time analysis of HWVir 

      Baran, A. S.; Østensen, R. H.; Telting, J. H.; Vos, J.; Kilkenny, D.; Vuckovic, M.; Reed, M. D.; Silvotti, R.; Jeffery, C. S.; Parsons, S. G.; V. S. Dhillon, V. S.; Marsh, T. R. (Oxford University Press, 2018)
      We analysed recent K2 data of the short-period eclipsing binary systemHWVir,which consists of a hot subdwarf-B type primary with an M-dwarf companion.We determined the mid-times of eclipses, calculated O–C diagrams, and ...

    • A spectroscopic analysis of the eclipsing nova-like EC 21178−5417 – discovery of spiral density structures 

      Kilkenny, D.; Khangale, Z. N.; Woudt, P. A. (Oxford University Press, 2020)
      We present phase-resolved optical spectroscopy of the eclipsing nova-like cataclysmic variable EC 21178−5417 obtained between 2002 and 2013. The average spectrum of EC 21178−5417 shows broad double-peaked emission lines ...
