Detectable Flashes from Light-Sail Transport Systems Between Habitable Exoplanets

• A 2015 study by the author and James Guillochon demonstrated that light sail propulsion systems can produce detectable radio transients.
• The study found that optimal beam frequencies for interplanetary travel are in the tens of gigahertz range, and such signals are most likely to be observed when exoplanets are in conjunction as viewed from Earth.
