Note: Due to the total solar eclipse and high seasonal demand in Valencia, participants are strongly encouraged to secure accommodation as early as possible.
On 12 August 2026, Spain will witness the first total solar eclipse visible from mainland Europe in almost 30 years. Beyond its beauty, a total eclipse is a striking reminder of a central theme in astrophysics: magnetic fields shape what we see, from faint plasma structures to bursts of energetic particles and coherent radio emission.
Like the Sun, many nearby stars and ultracool dwarfs are magnetically active across the electromagnetic spectrum. Over the last decade, new wideband, high-time-resolution radio facilities have transformed the field: auroral bursts, rotational modulation, and broadband polarimetry are now being used as quantitative probes of magnetic geometry, particle acceleration, stellar winds, and star–planet interactions—and they are opening a realistic path toward detecting and characterising exoplanetary magnetospheres.
To mark this rare celestial event, this conference will take place in Valencia, Spain from 10–12 August 2026, bringing together an international community working on stars, ultracool dwarfs, and radio exoplanet science. To foster deep discussion and sustained interaction, attendance will be capped at 50 participants. A dedicated eclipse field session will allow participants to share the totality experience together as part of the conference week.
