| Description | We propose joint XMM-Newton and HST observations of the nearby young G-type star HIP 67522, hosting a close-in Jupiter-size transiting exoplanet discovered with TESS, and possibly a second smaller body. The first confirmed planet in this young system (virgul17 Myr) is expected to be in a contraction phase toward its final size and possibly affected by 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 suitable to investigate evolutionary paths of exoplanets in the mass-radius diagram, and to provide constraints for planetary atmospheres modeling. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
