SuperWASP-N extrasolar planet candidates from fields 06h < RA < 16h
The Wide Angle Search for Planets (WASP) survey currently operates twoinstallations, designated SuperWASP-N and SuperWASP-S, located in theNorthern and Southern hemispheres, respectively. These installations aredesigned to provide high time-resolution photometry for the purpose ofdetecting transiting extrasolar planets, asteroids, and transientevents. Here, we present results from a transit-hunting observingcampaign using SuperWASP-N covering a right ascension (RA) range of06h < RA < 16h. This paper represents thefifth and final in the series of transit candidates released from the2004 observing season. In total, 729335 stars from 33 fields weremonitored with 130566 having sufficient precision to be scanned fortransit signatures. Using a robust transit detection algorithm andselection criteria, six stars were found to have events consistent withthe signature of a transiting extrasolar planet based on the photometry,including the known transiting planet XO-1b. These transit candidatesare presented here along with discussion of follow-up observations andthe expected number of candidates in relation to the overall observingstrategy.

Effective temperature scale and bolometric corrections from 2MASS photometry
We present a method to determine effective temperatures, angularsemi-diameters and bolometric corrections for population I and II FGKtype stars based on V and 2MASS IR photometry. Accurate calibration isaccomplished by using a sample of solar analogues, whose averagetemperature is assumed to be equal to the solar effective temperature of5777 K. By taking into account all possible sources of error we estimateassociated uncertainties to better than 1% in effective temperature andin the range 1.0-2.5% in angular semi-diameter for unreddened stars.Comparison of our new temperatures with other determinations extractedfrom the literature indicates, in general, remarkably good agreement.These results suggest that the effective temperaure scale of FGK starsis currently established with an accuracy better than 0.5%-1%. Theapplication of the method to a sample of 10 999 dwarfs in the Hipparcoscatalogue allows us to define temperature and bolometric correction (Kband) calibrations as a function of (V-K), [m/H] and log g. Bolometriccorrections in the V and K bands as a function of T_eff, [m/H] and log gare also given. We provide effective temperatures, angularsemi-diameters, radii and bolometric corrections in the V and K bandsfor the 10 999 FGK stars in our sample with the correspondinguncertainties.
