VCAS-Lecture , The Grand Tour: Properties of Planets Outside the Solar System

Tonight's topic: The Grand Tour: Properties of Planets Outside the Solar System-by Heather Knutson, Professor CalTech

We currently know of more than 10,000 planets and planet candidates orbiting nearby stars.  Many of these extrasolar planets look quite different than the planets in the solar system, including Jupiter-like gas giants on close-in orbits, `mini-Neptunes’ with puffy hydrogen-rich atmospheres, and rocky `super-Earths’ with masses many times that of Earth or Venus.   In my talk I will provide a guided tour of the exoplanet zoo as we understand it today, and describe ongoing efforts to characterize the properties of these distant worlds using both ground- and space-based telescopes.-
