Abstract

We explore the use of Integral Field Spectroscopy (IFS) for observing extrasolar planet transits. We show that IFS can improve the photometric accuracy in high S/N time series observations with respect to standard slit spectrophotometry. Ground based observations of HD209458b obtained with WHT + INTEGRAL during a transit have led to an accuracy in relative spectrophotometry (i.e line/continuum) not far from that expected by photon noise. This result indicates that these types of ground based observations can constrain the characterization of the transmission spectrum of extrasolar planets.
