Join us tomorrow at the AGU Fall Meeting for a session on direct imaging of habitable exoplanets that I organized with my colleagues Ramses Ramirez from Cornell University and David Black.
This session consists in a discussion on the potential of new and future facilities and modeling efforts designed to detect, image and characterize habitable exoplanets, studying their formation, evolution and also the existence of possible biospheres. Topics to be covered in this session include signs of exoplanet habitability and global biosignatures that can be sought with upcoming instrumentation; instrument requirements and technologies to detect these markers; strategies for target selection and prioritization; and impacts of planetary system properties, ground-based and space telescope architectures, and impacts of instrument capabilities on the yield of potentially inhabited exoplanets.
We have an oral session with 5 talks including two invited talks and a poster session 7 abstracts. Below a list.
We look forward to seeing you at the session this morning and this afternoon.
