Gaia DR3 Limits on Stellar Engine Technosignatures in Nearby Stars
An operating stellar engine that transfers momentum to its host star could produce an approximately persistent transverse acceleration during the Gaia Data Release 3 (DR3) observing epoch. We ask how common such stellar-engine-like accelerations could be among nearby stars. We define a quality-selected parent populatio...
