Descripción
Most of the known transiting extrasolar planets orbit slowly rotating F,
G or K stars. In here we report on the detection of a transiting planet
orbiting the bright, rapidly rotating A5 star HD15082, recently made by
SuperWASP. Time resolved spectroscopic observations taken during transit
show a hump caused by the planet crossing the line profile. From the
analysis of the spectra, we derive the radius of the planet and find
that it is orbiting retrograde in respect to the spin of the star.
Because of its small distance from an A5 star, this planet must be one
of the hottest planets known, which makes it relatively easy to detect
it in the IR. We thus tried to detect it using the TNG but did not
succeed. Using direct imaging, we search for possible companions, and
found one candidate.
