, 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.

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-

Magnetic games between a planet and its host star: the key role of topology [PDF]
, 2015 Magnetic interactions between a star and a close-in planet are postulated to be a source of enhanced emissions and to play a role in the secular evolution of the orbital system. Close-in planets generally orbit in the sub-alfv\'enic region of the stellar

Stellar Magnetism and starspots: the implications for exoplanets [PDF]
, 2013 Stellar variability induce by starspots can hamper the detection of exoplanets and bias planet property estimations. These features can also be used to study star-planet interactions as well as inferring properties from the underlying stellar dynamo ...

Observed effects of star-planet interaction [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractSince soon after the discovery of hot Jupiters, it had been suspected that interaction of these massive bodies with their host stars could give rise to observable signals. We discuss the observational evidence for star-planet interactions (SPI) of tidal and magnetic origin observed in X-rays and FUV.

Star-planet interaction through spectral lines [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractThe growth of spectroscopic observations of exoplanetary systems allows the possibility of testing theoretical models and studying the interaction that exoplanetary atmospheres have with the wind and the energetic photons from the star.

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 ...

HATS-18 b: An Extreme Short--Period Massive Transiting Planet Spinning Up Its Star [PDF]
, 2016 We report the discovery by the HATSouth network of HATS-18 b: a 1.980 +/- 0.077 Mj, 1.337 +0.102 -0.049 Rj planet in a 0.8378 day orbit, around a solar analog star (mass 1.037 +/- 0.047 Msun, and radius 1.020 +0.057 -0.031 Rsun) with V=14.067 +/- 0.040 ...
