A survey of exoplanet phase curves with Ariel

The ESA-Ariel mission will include a tier dedicated to exoplanet phase curves corresponding ~10% of the science time. We present here current observing strategy for studying with Ariel. define questions, requirements and list potential targets. also estimate precision curve reconstruction atmospheric retrieval using simulated curves. Based on this work, we found that full-orbit variations 35-40 exoplanets could be observed during 3.5-yr mission. This statistical sample would provide key constraints dynamics, composition, thermal structure clouds warm exoplanets, complementary scientific yield from spectroscopic transits/eclipses measurements.
