The session solicits contributions that report on nonthermal solar, planetary radio emissions, and radio wave generation at exoplanets. Coordinated multi-point observations from ground radio telescopes (e.g., LOFAR, LOIS, LWA1, URAN-2, UTR-2) and spacecraft plasma/wave experiments (e.g., BepiColombo, Solar Orbiter, Parker Solar Probe, UVSQ-Sat, Inspire-Sat 7, Cassini, Cluster, Demeter, Galileo, Juno, Stereo, Ulysses and Wind) are especially encouraged. Presentations should focus on radiophysics techniques which offer a wealth of diagnostic tools for detecting and measuring the magnetic field, the energetic particles, and the plasma properties in solar system regions, like the solar corona, the interplanetary medium and the magnetized auroral regions. Overview contributions on current states of radio investigation, scientific advances, and outlooks on the next decade are supported. Interest also extends to laboratory and experimental studies devoted to the comprehension of the generation mechanisms (e.g., cyclotron maser instability, mode conversion), and the acceleration processes (e.g., Alfven waves). Further preparations, evaluations, investigations, analyses of forthcoming space missions or nanosatellites (like Juice, SunRISE, UVSQ-Sat NG…) are also welcome.
