The Department of Physics and Astronomy hosts guest speaker Munazza Alam, Carnegie EPL Postdoctoral Fellow at Carnegie Earth & Planets Laboratory in Washington DC.  The presentation will be on the topic of ‘‘Characterizing Giant Planet Atmospheres with Hubble’’

Sponsored by Margaret B. Hays College Departmental Fund

Abstract:
In the past two decades, we have discovered over 4,000 planets outside of the Solar System, many of which are nothing like our own. One avenue for learning about the properties of these planets involves observing them when they pass in front of (transit) their host stars. During transit, a small fraction of starlight filters through the planet's atmosphere. By precisely measuring the spectrum of this filtered starlight, we can learn about the composition of the planet's atmosphere. Observing planets with this technique allows us to understand the makeup of their atmospheres as well as how they formed and evolved.
