Abstract:
Photometric transit surveys promise to complement the currently
known sample of extra-solar planets (ESPs) by providing additional
information on the planets and especially their radii. Here, we
present ESP candidates from one such survey called, the Wide Angle
Search for Planets (WASP) obtained with the SuperWASP wide-field
imaging system. Observations were taken with SuperWASP North located
in La Palma during the 2004 April to October observing season. The
data cover fields between 23 and 03h in RA at declinations above
+12°. This amounts to over ≫400000 stars with V magnitudes
8-13.5. For the stars brighter than 12.5, we achieve better than 1%
photometric precision. Here, we present 41 sources with low-amplitude
variability between ≫1 and 10mmag, from which we select 12 with
periods between 1.2 and 4.4d as the most promising ESP candidates.
We discuss the properties of these ESP candidates, the expected
fraction of transits recovered for our sample and implications
for the frequency and detection of hot-Jupiters.
Description:
The SW telescopes were designed to cover a large area of sky and
achieve photometric accuracy of a few mmag and improve on the success
of the prototype WASP0 instrument
