We aim to investigate prolonged rotation and activity in M dwarf (dM) stars dueto tidal interaction with close-in planets, an effect previously observed forSun-like stars hosting Hot Jupiters. We are conducting a survey of dM + whitedwarf (WD) wide binary systems to study the age-activity relationship for dMs,using WD as age calibrators. We aim follow-up cool WD + dM pairs identified inGaiaDR2, that will be also crucial for our main goal of testing the hypothesisof tidal interaction. We propose to use 288 ks of XMM-Newton observing time toderive X-ray luminosities as activity proxy for our dM targets. In addition, werequest 27 hours with X-shooter spectrograph at VLT to confirm their spectraltypes and to accurately determine their ages via their WD companions.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
