The XUV environment of the young exoplanet HIP 67522b

We propose joint XMMNewton and HST observations of the nearby young Gtype starHIP 67522, hosting a closein Jupitersize transiting exoplanet discovered withTESS, and possibly a second smaller body. The first confirmed planet in thisyoung system (virgul17 Myr) is expected to be in a contraction phase toward its finalsize and possibly affected by photoevaporation. Our immediate objective is toreconstruct the full XUV spectrum, and to assess the spectral and timevariability of the host star. In this way we will characterize its activitylevel and the dose of highenergy irradiation in the planetary environment. Thissystem is particularly suitable to investigate evolutionary paths of exoplanetsin the massradius diagram, and to provide constraints for planetary atmospheres modeling. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
