Stellar magnetic activity – Star-Planet Interactions [PDF]
EPJ Web of Conferences, 2015 Stellar magnetic activity is an important factor in the formation and evolution of exoplanets. Magnetic phenomena like stellar flares, coronal mass ejections, and high-energy emission affect the exoplanetary atmosphere and its mass loss over time.

Astronomy & Astrophysics, 2021 Context. Tidal interactions and planetary evaporation processes impact the evolution of close-in star–planet systems. Aims. We study the impact of stellar rotation on these processes. Methods. We compute the time evolution of star–planet systems consisting of a planet with an initial mass between 0.02 and 2.5 MJup (6 and 800 MEarth) in a quasi-circular

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.

The birth environment of planetary systems [PDF]
Royal Society Open Science, 2020 Star and planet formation are inextricably linked. In the earliest phases of the collapse of a protostar, a disc forms around the young star and such discs are observed for the first several million years of a star’s life.

, 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.

Star-planet Interactions [PDF]
Astronomy & Astrophysics, 2016 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 ...

ROME. III. The Arecibo Search for Star–Planet Interactions at 5 GHz
The Astrophysical Journal, 2023 After nearly three decades of discovery, many exoplanetary systems have been studied and characterized in detail with one important exception: exoplanet magnetism.

Star-planet interactions [PDF]
Astronomy & Astrophysics, 2017 The surface rotations of some red giants are so fast that they must have been spun up by tidal interaction with a close companion, either another star, a brown dwarf, or a planet. We focus here on the case of red giants that are spun up by tidal interaction with a planet.

GJ 357 d: Potentially Habitable World or Agent of Chaos?
The Astronomical Journal, 2023 Multiplanet systems provide important laboratories for exploring dynamical interactions within the range of known exoplanetary system architectures. One such system is GJ 357, consisting of a low-mass host star and three orbiting planets, the outermost ...
