Narrowband Signals During Planetary Occultations: A Proof-of-Concept for Interplanetary Eavesdropping

To the point

Nick Tusay proposes listening for narrowband chatter that leaks when one exoplanet partially blocks another during occultations as a focused SETI approach, while Seth Shostak cautions that a confident identification would require rigorous testing and might not be addressed to us, Rebecca Charbonneau notes our bias toward human signaling and that future work could explore other channels like gravitational waves, and even if decoding is very hard, modulation patterns could still reveal details about the planets or civilizations.
