Andrew Howard, professor of astronomy at the California Institute of Technology, will be the featured speaker at an upcoming Department of Physics and Astronomy colloquium. His talk is titled, "Earth-Size Exoplanets."
Earth-size exoplanets and their slightly larger ‘super-Earth’ cousins are the most abundant planets orbiting close to Sun-like stars. These planets have diverse physical compositions, unusual atmospheres, and poorly understood origins. Howard's talk will trace the discovery and early characterization of these small worlds through Doppler and transit surveys, and look forward to future discoveries with instruments such as the Keck Planet Finder.
There will be refreshments starting at 3:30 p.m.
