Description We propose X-ray observations of nearby F-G-K young (20-40 Myr) stars hosting
transiting exoplanets, recently discovered by TESS and Kepler (K2), and included
in follow-up campaigns with HARPS@ESO 3.6m and HARPS-N@TNG. DS Tuc and HD 33512
host super-Earth/Neptune mass planets with inflated atmospheres, due to strong
irradiation from their host stars. V1298 Tau harbors a warm Jupiter still in
contraction toward its final size. Our immediate objective is to assess X-ray
spectral and time variability of the host stars, so to characterize their
activity level and the dose of high-energy radiation received by very young
planets. Final goals are the determination of evolutionary paths of exoplanets
in the mass-radius diagram, and constraints for modeling planetary atmospheres.

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.
