摘要:

The observational scrutiny of the atmospheres of exoplanets is now a legitimate field of inquiry, which has motivated their theoretical study. In this review talk, I will summarise and highlight the state of the art of both observations and theory of exoplanetary atmospheres. The review is organised into eras, starting from the birth of spectrophotometry to the upcoming set of next-generation exoplanet hunters and characterisers. On the observational side, I will review spectrophotometry, phase curves, eclipse mapping, direct imaging and ultra-high-resolution spectroscopy. On the theoretical side, I will review atmospheric radiation, chemistry and circulation (fluid dynamics). I will discuss the problem of bright stars and why we need the next-generation of exoplanet hunting machines (CHEOPS, TESS and PLATO) to build up a better target list for atmospheric characterisation. Finally, there will be a discussion of the habitable zone and also how the conversations between the scientists from different sub-disciplines need to be more constructive. (The talk will consist of 32 slides.)
