Results from the Wide Angle Search for Planets Prototype (WASP0) - II. Stellar variability in the Pegasus field
Recent wide field photometric surveys, which target a specific field forlong durations, are ideal for studying both long- and short-periodstellar variability. Here, we report on 75 variable stars detectedduring the observations of a field in Pegasus using the Wide AngleSearch for Planets Prototype (WASP0) instrument, 73 of which are newdiscoveries. The variables detected include 16 δ Scuti stars, 34eclipsing binaries, 3 BY Draconis stars and 4 RR Lyraes. We estimatethat the fraction of stars in the field brighter than V~ 13.5 exhibitingvariable behaviour with an amplitude greater than 0.6 per cent rms is~0.4 per cent. These results are compared with other wide field stellarvariability surveys, and implications for detecting transits due toextra-solar planets are discussed.
