"High-resolution spectroscopy: A powerful tool for characterizing exoplanets and their atmospheres"
The characterization of an exoplanet atmosphere can reveal the chemical composition of the atmosphere, its reflective properties, the presence of condensates, its temperature structure, and possible rotation and global circulation. Those may be linked to the formation and evolutionary history of the planet, and are needed to understand its global climate.
Ground-based high-dispersion spectroscopy has proven to be an effective method to probe the atmospheres of both transiting and non-transiting hot Jupiters, as well as young, wide-orbit gas giants discovered with direct imaging. With a sufficiently high spectral resolution, the molecular features are resolved into individual lines. This allows robust identification of the molecules through line matching with template spectra. Additional insight is gained from the shape of the spectral lines.
In this talk, I will review the growing field of high-resolution exoplanet characterization and give you an idea of what to expect in the future
Please note: Should you require any accommodations to ensure equal access and opportunity related to this event please contact Stacy Tiburzi at 734-764-3440 or stibu@umich.edu.
Tea will be served beforehand from 3:00-3:30pm in 411 West Hall.
