The first confirmed planet in this young system is expected to be in a contraction phase toward its final size and possible photoevaporation. Our immediate objective is to reconstruct the full XUV spectrum, and to assess the spectral and time variability of the host star. In this way we will characterize its activity level and the dose of high-energy irradiation in the planetary environment. This system is particularly compelling to investigate evolutionary paths of exo- planets in the mass-radius diagram, and to provide constraints for planetary atmospheres modeling. This is a coordinated observation with XMM-Newton. We ask observations with HST/COS joint and simultaneous with XMM-Newton observations of the young G-type star HD . We aim to acquire high resolution spectra in the band 1180 - 1450 Angstrom with the G130M grating (central wavelength of 1291 Angstrom) during 3 HST orbits. The declination of the star ensures an average HST visibility of about 50' per orbit, available for science exposures. We intend to measure the intensity of ion lines from Si II, Si III, Si IV, CII , CIII, NV falling in the above wavelength range. Co-I I. Pillitteri has already gained expertiese with the analysis of HST/COS spectra of the target HD 189733. The PI and most of the co-Is are involved in the HST program 16490 for observation of V1298 Tau, having similar characteristics with the present program and target.
