Stellar Space Weather May Blur Narrowband Technosignals, Reframing SETI Searches
To the point
Vishal Gajjar and Grayce C. Brown of the SETI Institute say space weather around stars can broaden and weaken ultra-narrow radio signals before they leave their system, making them harder to spot at Earth, and they argue that red dwarfs, being especially active, require adjusting detection thresholds and bandwidths to account for these distortions.
