New exoplanet-informed research sets clearer bounds on the search for radio technosignatures
A new study leverages the NASA Exoplanet Archive and planetary system simulations to make narrowband SETI searches more efficient.
October 23, 2023, Mountain View, CA -- In a new study published in the Astronomical Journal, researchers used the known population of exoplanets and extrapolated to the much larger, unknown population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). The prior recommendation for the threshold “drift rate” contribution, caused by a planet’s motion around its host star, was 200 nHz. In this work, lead ...
