The component star masses in RW Tri
Poole, T.; Mason, K.O.; Ramsay, G.; Drew, J.E.; Smith, R.C. (2003) -
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 ... -
The OmegaWhite Survey for Short-Period Variable Stars - I : Overview and First Results
Macfarlane, S. A.; Toma, R.; Ramsay, G.; Groot, Paul J.; Woudt, P. A.; Drew, J.E.; Barentsen, G.; Eisloffel, J. (2015-11-21)We present the goals, strategy and first results of the OmegaWhite survey: a wide-field high-cadence g-band synoptic survey which aims to unveil the Galactic population of short-period variable stars (with periods <80 min), ... -
RApid Temporal Survey (RATS) II. Follow up observations of four newly discovered short-period variables
Ramsay, G.; Napiwotzki, R.; Hakala, P.; Lehto, H. (2006) -
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 ...
