High-Contrast Imaging at TMT Gas giants, ice-giants, terrestrial planets, exomoons, polarization, transits, weather, surface mapping, biomarkers, disks, planet formation, … High-Contrast/ExAO breakout session Stanimir Metchev, UWO S. Sengupta O. Guyon O. Guyon PSI PFIX • Drivers: characteriza.on of exoplanets in reflected light and thermal emission • Goal: Biosignatures on terrestrial planets in nearby HZs • Constraining composi.on and forma.on pathways • Circumstellar disks, solar system objects, AGB star ouFlows • General-purpose 2.5-5 um imaging, spectroscopy capabili.es not in first-light instruments • Modularity • Core capabili.es support different science instruments • Upgrade paths to accommodate new technology • Fiber feeds allow straighForward use of instruments deployed and tested on smaller telescopes • Rela.vely compact • Diffrac.on-limited, narrow field-of-view op.cs • Allows for phased development and deployment PSI concept PSI-Green PSI-Red PSI-Blue PSI-Red Woofer DM Cold Vis WFS IR WFS Coronagraph Tweeter Coronagraph DM 8-13 μm Imager Cold 0.6-1.8 μm Coronagraph IFU/Imager 0.6-1.8 μm High-Res 2-5 μm 2-5 μm High-Res IFU/Imager A.
