DESCRIPTION:Tidal interaction between a hot Jupiter and its host star resu
 lts in  stellar oscillations which produce both a radial velocity signal a
 nd a variation of the stellar flux.  To compute the perturbation at the su
 rface of the star accurately\, non-adiabaticity and departure from the equ
 ilibrium tide have to be taken into account.   We explain how the modelled
  oscillations are converted into photometric and spectroscopic signals\, a
 nd present results for both general trends and specific systems.
