    • New short-period stellar pulsators at large Galactocentric distances 

      Ramsay, G.; Barclay, T.; Napiwotzki, R.; Barclay, T.; Cropper, M.; Hakala, P.; Potter, S. (2011-10-01)
      We report the discovery of 31 blue, short-period, pulsators made using data taken as part of the Rapid Temporal Survey (RATS). We find that they have periods between 51 and 83 min and full amplitudes between 0.05 and ...

    • RAT J1953+1859: a dwarf nova discovered through high amplitude QPOs in quiescence 

      Ramsay, G.; Hakala, P.; Barclay, T.; Wheatley, P.J.; Marshall, G.; Lehto, H.; Napiwotzki, R.; Nelemans, G.; Potter, S.; Todd, I. (2009)
      We report the discovery of an accreting binary, RAT J1953+1859, made during the RApid Temporal Survey (RATS) on the Isaac Newton Telescope. It showed high amplitude (0.3 mag) quasi-periodic oscillations on a time-scale of ...
