Title: The case of the missing molecules -- how atmospheric chemistry modeling can solve some mystery of exoplanets
Exoplanet research has revolutionized how we think about life and planets. The ground- and space-based telescopes, such as HST and Spitzer, have allowed us to progress from the stage of detection to probe fundamental properties of the planets. The upcoming space telescopes, such as JWST and ARIEL, promise a bright outlook for characterizing exoplanet atmospheres. We are in an exciting era to study exoplanet atmospheres, driven by the goal of understanding the principal physical and chemical processes and ultimately identifying habitable worlds. In this talk, I will review the role of chemical modeling in helping us understand the atmosphere. I will summarize the highlights in my recent work Tsai et al. (2021a), Tsai et al. (2021b) on various chemical processes in diverse exoplanet atmospheres, and what we can learn about the surface conditions when certain gases are present or missing. Lastly, I will discuss the modeling challenges and how we can go beyond the limit of 1D models.
