Radio observations hint at hidden micro-flares on AU Mic
A short VLA observing run on the single star AU Mic found strong variability even during selected quiet intervals, along with two clear flares. The authors interpret the pattern as evidence that many small, unresolved flares may help sustain the star’s radio emission, but the result is based on one star at one epoch.
