  Data from the Kepler satellite (Q0-Q11) are used to study HAT-P-7. The
satellite's data are extremely valuable for asteroseismic studies of stars and
for observing planetary transits; in this work we do both. An asteroseismic
study of the host star improves the accuracy of the stellar parameters derived
by Christensen-Dalsgaard et al. (2010), who followed largely the same procedure
but based the analysis on only one month of Kepler data. The stellar
information is combined with transit observations, phase variations and
occultations to derive planetary parameters. In particular, we confirm the
presence of ellipsoidal variations as discovered by Welsh et al. (2010), but
revise their magnitude, and we revise the occultation depth (Borucki et al.
2009), which leads to different planetary temperature estimates. All other
stellar and planetary parameters are now more accurately determined.
