Guest Speaker: Mr. Yoni Brandi, PhD candidate, University of Kansas in Lawrence.
Summary: In this webinar, Yoni begins with an explanation of exoplanets and how they are observed, after which he talks about planetary atmospheres. Yoni describes how, when a planet transits its star, the light of the star shines through the planet’s atmosphere, which can be analyzed using a spectrograph. Depending on the chemical composition of the atmosphere, the spectrograph will show the corresponding absorption lines for that planet’s atmosphere chemicals. The radiation from the star breaks down the hydrocarbons in the planet’s clouds, creating a haze that scatters the spectral lines of that planet. This data can help determine how hot the planet is and how clear its atmosphere is.
If you are interested in exoplanetary atmospheres, this video will open your eyes to the fascinating study of atmospheric haze models and how they are used to analyze the atmospheric conditions of exoplanets. We hope you enjoy it!
