Huntingdon AAUW Presents: Jennifer Carter, Thermal Radiation of Worlds Beyond our Solar System
March 10 @ 7:00 pm - 8:30 pm
Jennifer Carter, assistant professor of physics at Susquehanna University, won a research publication grant from AAUW. Her talk will focus on how we can describe the temperature distribution of exoplanets using their emitted light.
Since we can now detect the presence of planets orbiting distant stars, we want to determine as many details of them as possible. Planets orbiting far-away stars mirror the planets of our solar system, but many do not match our previous expectations. For example, the first exoplanets discovered orbit their host stars in less than 3 days whereas the orbit of Mercury is 88 days in length. Since these first discoveries, we have launched several missions to study exoplanets using a variety of techniques.
In this talk, Carter will focus on one technique that offers the opportunity to detect light emitted directly by the exoplanet, including thermal light. Like a hot iron, closely orbiting exoplanets are hot enough to glow with visible light. As instrumental precision increases, we will require more accurate models of this thermal radiation. After reviewing current methods of modeling thermal radiation, Carter will introduce her new model and compare how well each model explains data gathered from exoplanet systems under different conditions.
The talk will be held on Zoom. Register in advance for this meeting: https://us02web.zoom.us/meeting/register/tZcld-GtqzIuEtZKc9gqzMG_-3zFUjt_OAuf.
