Time-variable Electromagnetic Star–Planet Interaction: The TRAPPIST-1 System as an Exemplary Case
@article{Fischer2019TimevariableES, title={Time-variable Electromagnetic Star–Planet Interaction: The TRAPPIST-1 System as an Exemplary Case}, author={Christian Fischer and Joachim Saur}, journal={The Astrophysical Journal}, year={2019} }
Exoplanets sufficiently close to their host star can in principle couple electrodynamically to the star. This process is known as electrodynamic star-planet interaction (SPI). The expected emission associated with this coupling is however difficult to observe due to the bright intrinsic stellar emission. Identification of time-variability in the stellar lightcurve is one of the most promising approaches to identify SPI. In this work we therefore systematically investigate various mechanisms and…
