Seminar by Genaro Suárez, AMNH

The observation and modeling of substellar objects such as brown dwarfs and exoplanets allow us to understand the physics and chemistry that govern their atmospheres, which is essential to explain their diversity. In this talk, I will show progress we have made in explaining the appearance of extrasolar worlds, from the hottest (~2300 K) to the coldest (~400 K) ones. Particularly, I will present results on the formation, composition, evolution, and distribution of dust clouds that shape the emergent spectra of the warmest brown dwarfs and exoplanets using Spitzer mid-infrared spectra. In addition, I will show JWST data that are guiding us in understanding the physical and chemical processes that sculpt the coldest extrasolar atmospheres.
