Direct Imaging allows for unambiguous characterization of exoplanets and their atmospheres. With the ELT coming up in the next decade we will be able to directly image several tens of planets. [[BR]][[BR]]One of the challenges to overcome is the slowly drifting non-common path error which is limiting the detection of exoplanets at a few lambda/D. High-resolution spectroscopy can be used to overcome these speckles and probe closer and deeper to the star and at the same time characterize the exoplanet. To that end we have developed the Leiden EXoplanet Intrument (LEXI), a pathfinder for the ELT/EPICS, aimed at overcoming the huge planet/star contrasts at a few lambda/D and characterizing exoplanets with high-resolution spectroscopy. During this talk Sebastiaan Haffert will show and discuss the results obtained with LEXI.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2019S1/2019-02-22_LEXI.pdf Slides: English][[BR]]Questions: German, English || |
