The corona of GJ 1151 in the context of star–planet interaction [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The low-mass star GJ 1151 has been reported to display variable low-frequency radio emission, which has been interpreted as a signpost of coronal star–planet interactions with an unseen exoplanet. Here we report the first X-ray detection of GJ 1151’s corona based on the XMM–Newton data.

Signs of magnetic star-planet interactions in HD 118203
Astronomy and AstrophysicsContext. Planetary systems with close-in giant planets can experience magnetic star-planet interactions that modify the activity levels of their host stars. The induced activity is known to strongly depend on the magnetic moment of the interacting planet.

Star-planet tidal interaction and the limits of gyrochronology [PDF]
Astronomy and Astrophysics, 2019 Context. Age estimation techniques such as gyrochronology and magnetochronology cannot be applied to stars that have exchanged angular momentum with their close environments. This is especially true for a massive close-in planetary companion (with a period of a few days or less) that could have been strongly impacted by the rotational evolution of the ...

Among the numerous lessons learnt thanks to the CoRoT mission, it is now clear that stellar systems should be considered as a whole, i.e. including both the planets and their host star. While the communities interested in exo-planetary sciences and stellar physics were bound together by the same instrument, CoRoT, it soon appeared that they share a ...

In Chaps. 10 and 11, I surveyed the various ways in which a host star’s radiation and wind can erode an exoplanet’s atmosphere, change its chemistry, and thereby determine whether the exoplanet could be habitable. I now turn to the question of whether an exoplanet can change the properties of its host star, in particular, its rotation rate, UV and X ...
