Gaidos, Eric (2017): Transit Detection of a „Starshade“ at the Inner Lagrange Point of an Exoplanet. (in press). In: Earth and Planetary Astrophysics.
„Reflectors or scatterers placed near Earth’s inner Lagrange point (L1) have been proposed as a ‚geo-engineering“ solution to anthropogenic climate change and an advanced version of this could modulate incident irradiation over many Gyr or „rescue“ a planet from the interior of the habitable zone. The distance of the starshade from the planet that minimizes its mass is 1.6 times the Earth-L1 distance. Such a starshade would have to be similar in size to the planet and the mutual occultations during planetary transits could produce a characteristic maximum at mid-transit in the light-curve.“
