    Detection of exoplanets: exploiting each property of light by Rouan, Daniel, Lagrange, Anne-Marie

    Published 2023-08-01
    “…Up to now and probably for still a long time, the only support of information used to detect exoplanets has been the analysis of light, either visible or infrared. In the vast majority of cases it is the light from a star and not the light from the planet itself which is used, because the huge contrast in brightness between the star and a planet orbiting it as well as the extremely short angular distance between them makes direct imaging a real challenge. …”
