Description
A key question in astronomy is whether there are habitable planets around other stars. Exoplanet habitability is largely determined by the stellar environment, with stellar eruptions buffeting exoplanets while the stellar wind slowly erodes the upper layers of the atmosphere. Traditional methods struggle to directly measure the stellar environment, in particular for low-mass stars. However, by detecting radio emission from a star, we can directly measure the magnetic field strength or the plasma density in the system, providing a unique window into the conditions around these stars. In this talk, I will present an overview of the recent results in the field of low-frequency stellar radio astronomy, with a focus on LOFAR imaging surveys.
