AAAS 2016: Planet Formation With Radio Eyes

AAAS 2016 Science Symposium: Planet Formation With Radio Eyes

Radio-wavelength emission is little affected by intervening dust and gas and observations with radio telescopes are key to improving our understanding of star and planet formation and the dust-shrouded environments where these processes occur. Astronomers around the world are exploring new discovery space and scientific frontiers using much more capable arrays and large, single dish radio telescopes, including the Atacama Large Millimeter/submillimeter Array, Very Large Array, Plateau de Bure Interferometer, 100-m Green Bank Telescope, and 45-m Nobeyama Radio Observatory. The much improved sensitivity, resolution, and imaging quality of these telescopes are enabling a revolution in our understanding of the physics and chemistry of star and planet formation. Recent radio images have revealed telltale tracks in heavily obscured nearby disks, for example, that are presumably signatures of planet formation. Scientists are now probing how, where, and when planets form and are analyzing the links between planetary system architecture and the properties of the parent circumstellar disk. Though the relationship of planetary to stellar masses remains obscure, it is clear that most stars host planets. This symposium will describe the state-of-the-art radio-wavelength observing campaigns being used by astronomers to probe planet formation and will sample the new scientific results that radio telescopes are yielding in this exciting field.
