  • Koen, Chris (Oxford University Press, 2007)
    HE 0230−4323 is a known binary, consisting of a subdwarf star and a companion which is not observable in the optical. Photometric measurements reported in this paper have shown it to be both a reflection-effect and a ...
  • Kilkenny, David; Koen, Chris; Worters, H. (Oxford University Press, 2010)
    HE 0230−4323 is a hot sdB star in a binary system. An earlier work demonstrated that the light curve of the system shows a strong (∼4 per cent) reflection effect and also appears to exhibit photometric variations of the ...
