Starshades as technosignatures in direct imaging phase curves: application to the Habitable Worlds Observatory targets
A star’s luminosity increases as it evolves along the main sequence (MS), which inevitably results in a higher surface temperature for planets in orbit around the star. Technologically advanced civilizations may tackle this issue by installing artificial structures – starshades – which can reduce the radiation received by the planet. Starshades, if they exist, are potentially detectable with curre
