    • Hot white dwarfs and pre-white dwarfs discovered with SALT 

      Jeffery, C. Simon; Werner, K.; Kilkenny, Dave (Oxford University Press, 2023)
      The Southern African Large Telescope survey of helium-rich hot subdwarfs aims to explore evolutionary pathways among groups of highly evolved stars. The selection criteria mean that several hot white dwarfs and related ...

    • News from the EREBOS project 

      Schaffenroth, Veronika; Barlow, Brad; Geier, Stephan; Vučković, Maja; Kilkenny, Dave; Schaffenroth, Johannes (De Gruyter Open, 2017)
      Planets and brown dwarfs in close orbits will interact with their host stars, as soon as the stars evolve to become red giants. However, the outcome of those interactions is still unclear. Recently, several brown dwarfs ...

    • The orbital periods of aa dor and ny vir 

      Kilkenny, Dave (Oxford University Press, 2011)
      New timings of eclipses made between 2000 and 2010 are presented for two binary systems with hot subdwarf primary stars. In the case of AA Dor, an sdOB star with a very cool secondary, the period is found to be constant ...

    • A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres – contamination analysis and new sdB pulsators 

      Sahoo, Sumanta Kumar; Baran, Andrzej; Kilkenny, Dave (Oxford University Press, 2023)
      We present an update on the variable star survey performed on the TESS 30 min Full Frame Image (FFI) data reported by our first two papers in this series. This update includes a contamination analysis in order to identify ...
