Astronomy Colloquium - Wendy Panero
The Effect of Stellar Abundance Ratios on Rocky Planet StructureWendy Panero (OSU) The surface environment, including habitability, of terrestrial planets is dependent upon stellar insolation as well as atmospheric chemistry, specifically water and carbon dioxide. Surface-to-interior mass flux of water and carbon regulates atmospheric compositions, regulating climate and providing weathering of rock for nutrient transport necessary for life. Such interior dynamics, such as in plate tectonics on Earth, is a consequence of convective heat transfer generated within the 2900 km thick solid silicate mantle. Exoplanet properties are presently limited to measurements of mass and radius. I will present an approach by which we can use the mass, radius, and composition of the planet host star to establish conditions under which exoplanets may or may not be habitable. Conversely, this approach may be used to target stars for the search for habitable planets. Coffee & Donuts will be served at 3:30pm in 4054 McPherson Lab
