Abstract:
Recent wide field photometric surveys, which target a specific field
for long durations, are ideal for studying both long- and short-period
stellar variability. Here, we report on 75 variable stars detected
during the observations of a field in Pegasus using the Wide Angle
Search for Planets Prototype (WASP0) instrument, 73 of which are new
discoveries. The variables detected include 16 δ Scuti stars, 34
eclipsing binaries, 3 BY Draconis stars and 4 RR Lyraes. We estimate
that the fraction of stars in the field brighter than V∼13.5
exhibiting variable behaviour with an amplitude greater than 0.6% rms
is ∼0.4%. These results are compared with other wide field stellar
variability surveys, and implications for detecting transits due to
extra-solar planets are discussed.
Description:
The first observing run of WASP0 took place on La Palma, Canary
Islands, during 2000 June 20 to 2000 August 20.

Note (1): The instrument uses a clear filter which has a slightly higher
red transmission than blue.
Note (2): Variables for which there is an associated question mark have
a small uncertainty regarding the classification.
Variables for which a suitable classification could not be assigned
are designated as unknown (U).
