Charting Technosignatures with the Hertzsprung–Russell Diagram: A Dyson-Sphere Search Around Red and White Dwarfs
To the point
Researchers propose using the Hertzsprung-Russell diagram to hunt for Dyson‑like megastructures around M‑type red dwarfs or white dwarfs, which would re‑radiate energy as cooler, dimmer infrared signals detectable by WISE and JWST, while noting natural explanations and the need for careful verification, echoing Freeman Dyson’s idea.
