Description

Despite an increasing recognition of the importance of stellar magnetic activity for determining the space weather exoplanets experience, long-term radio monitoring campaigns of active radio stars remain sparse. At the same time, the Westerbork Synthesis Radio Telescope (WSRT) is currently underutilized. We know that magnetically active low-mass stars produce radio flares that can interact with the magnetic fields of potential exoplanets. Understanding such Star-Planet-Interactions is crucial for assessing the impact of stellar weather on exoplanet habitability. In this talk, I will detail my Masters project in which I have been monitoring a small sample of radio stars for long periods. This allows us to study their radio variability over long timescales, such as the burst strength distributions, burst phenomenology, and emission characteristics. I will detail the process of getting the WSRT in a position to be able to conduct this science. This work also explores a potential new science application for WSRT single dishes studying radio activity in low-mass stars over long observation campaigns.
