AIP Conference Proceedings, 2009 Much effort has been invested in recent years, both observationally and theoretically, to understand the interacting processes taking place in planetary systems consisting of a hot Jupiter orbiting its star within 10 stellar radii. Several independent studies have converged on the same scenario: that a short-period planet can induce activity on the ...

III.9 Star-planet Interactions [PDF]
, 2016 This book is dedicated to all the people interested in the CoRoT mission and the beautiful data that were delivered during its six year duration. Either amateurs, professional, young or senior researchers, they will find treasures not only at the time of this publication but also in the future twenty or thirty years. It presents the data in their final

Searching for Star-Planet interactions within the magnetosphere of HD 189733
, 2010 HD 189733 is a K2 dwarf, orbited by a giant planet at 8.8 stellar radii. In order to study magnetospheric interactions between the star and the planet, we explore the large-scale magnetic field and activity of the host star. We collected spectra using the ESPaDOnS and the NARVAL spectropolarimeters, installed at the 3.6-m Canada-France-Hawaii telescope

On close-in magnetized star-planet interactions [PDF]
, 2012 We present 2D magnetohydrodynamic simulations performed with the PLUTO code to model magnetized star-planet interactions. We study two simple scenarios of magnetized star-planet interactions: the unipolar and dipolar interactions.

Astronomy & Astrophysics, 2022 Context. Electromagnetic star-planet interaction (SPI) describes the phenomenon of a planet coupling to its host star via electromagnetic forces. Alfvén waves can establish such a coupling by forming Alfvén wings. Star-planet interaction allows for phenomena that we do not otherwise know from the Solar System.

ON THE DETECTABILITY OF STAR-PLANET INTERACTION [PDF]
The Astrophysical Journal, 2012 Magnetic (or tidal) interactions between "hot Jupiters" and their host stars can potentially enhance chromospheric and coronal activity. An ideal testbed for investigating this effect is provided by the extreme WASP-18 system, which features a massive (~10 times Jupiter) close-in (~1 day period) transiting planet orbiting a young F6 star. Optical and X-

Search for the Star-Planet Interaction [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractWe analyse the chromospherical activity of stars with extrasolar planets and search for a possible correlation between the equivalent width of the core of the Ca II K line and orbital parameters of the planet. We found statistically significant evidence that the equivalent width of the Ca II K line reversal, which originates in the stellar ...

, 2023 The exoplanet revolution that began three decades ago has drastically changed our knowledge of the extra-solar systems. Today, we face an extreme diversity and complexity of these systems that can only be understood through the intimate link that exists between the planets and their host stars.
