Direct imaging of habitable planets with ELTs

Olivier Guyon
The unprecedented angular resolution soon to be offered by extremely large telescopes (ELTs), together with recently developed high contrast imaging techniques (coronagraphy and wavefront control), can enable direct imaging and spectroscopic characterization of potentially habitable planets around nearby M-type stars. While the habitable zone of M stars is challenging to resolve, the planet to star contrast and the apparent brightness of the planet are highly favorable, thus providing the only opportunity for direct imaging and...
