Performance and robustness for future
exoplanet imagers

Speaker : Lucie Leboulleux


Abstract :

The next objective in exoplanet direct imaging is to study dozens of rocky
exoplanets orbiting M-type to solar-type stars (F/G/K), in order to build
theories about their origins, evolution, diversity, and habitability. The
performance required to characterize rocky planets cannot be achieved
with current state-of-the-art technologies and will rely on ongoing
developments in high-contrast imaging systems, which are challenging to
optimize. With great performance comes great sensibility: maintaining the
performance over time is as crucial as achieving it initially, and mitigating
time-varying and quasi-static aberrations is a key consideration when
designing future high-contrast instruments. During this presentation, I will
discuss current research in instrumentation for exoplanet imaging for
future space and ground-based telescopes, with a focus on performance
maintenance.
