The inflated planet is exposed to high irradiation and it plays a key role in determining the overall activity of the parent star. To date, HD189733 is one of the few cases where star-planet interaction (SPI) is at work. We have strong suggestion that SPI is enhancing the stellar X-ray activity and variability in a systematic way. HST is the best facility to accomplish our scientific program. It can effectively probe the amount of mass evaporating from the planet, and determining the dynamics of the gas around the planet, confirming or disproving currenct state-of-art MHD models of this system. ------------------------------------------------------------------------------------ Observations Description ------------------------ We aim to obtain time resolved spectroscopy of the planet bearing star HD189733A, at phases 0.5-0.65 of the planet with COS/G130M. We require five consecutive orbits to observe the egress of the planet from secondary transit. We observe in TIME-TAG mode to follow any changes in the line profiles in 1100-1400 Angstroms range.
