Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. IÅık, A. Valio, A. Strugarek +10
Understanding stellar magnetic activity is central to exoplanet science in two ways: it sets the dynamic astrospheric boundary condition governing planetary space environments, and…
Radio emission from star-planet interactions
H. K. Vedantham, A. Strugarek, C. K. Louis +12
Stars interact with their exoplanets though gravity, radiation, plasma and magnetic fields. Stellar plasma and magnetic fields impose electrodynamic effects on exoplanet atmosphere…
Sungrazer comets as analogs of star-planet magnetic interactions
L-S. Guité, A. Strugarek, A. J. Finley +5
Star-planet magnetic interactions (SPMIs) can transfer energy from an exoplanet to its host star via Alfvén waves when the planet orbits within a sub-Alfvénic stellar wind. Simil…
A predictive framework for realistic star planet radio emission in compact systems
J. J. Chebly, C. K. Louis, A. Strugarek +2
Radio emission from star planet interactions (SPI) beyond our solar system has yet to be firmly detected, primarily due to challenges such as weak signals, directional beaming effe…
Non-transiting exoplanets as a means of understanding star-planet interactions in close-in systems
C. Gourvès, S. N. Breton, A. Dyrek +5
Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic interactions b…
A circularly polarized low-frequency radio burst from the exoplanetary system HD 189733
X. Zhang, P. Zarka, J. N. Girard +17
We aim to detect low-frequency radio emission from exoplanetary systems, which can provide insights into planetary magnetic fields, star-planet interactions, stellar activity, and…
