Stellar Space Weather Broadens Ultra-Narrow Signals, Reframing SETI Search Strategies
To the point
Vishal Gajjar and Grayce Brown explain that space weather around distant stars can blur ultra-narrow radio signals before they reach Earth, especially for M-dwarfs, so SETI searches should be sensitive to broader signals and use a framework that estimates how much broadening to expect across star types and observing frequencies, based on solar-system measurements.
