Abstract:
The Wide Angle Search for Planets (WASP) survey currently operates two
installations, designated SuperWASP-N and SuperWASP-S, located in the
Northern and Southern hemispheres, respectively. These installations
are designed to provide high time-resolution photometry for the
purpose of detecting transiting extrasolar planets, asteroids, and
transient events. Here, we present results from a transit-hunting
observing campaign using SuperWASP-N covering a right ascension (RA)
range of 06h<RA<16h. This paper represents the fifth and final in
the series of transit candidates released from the 2004 observing
season. In total, 729335 stars from 33 fields were monitored with
130566 having sufficient precision to be scanned for transit
signatures. Using a robust transit detection algorithm and selection
criteria, six stars were found to have events consistent with the
signature of a transiting extrasolar planet based on the photometry,
including the known transiting planet XO-1b. These transit candidates
are presented here along with discussion of follow-up observations and
the expected number of candidates in relation to the overall observing
strategy.
Description:
The SuperWASP-N instrument is a robotic observatory designed to
provide precision photometry for large areas of sky. First light was
achieved in 2003 November and observations have continued until the
present time.
