"Zooming in on planet-forming disks around young stars with ALMA"
Join our pre-Colloquium Coffee Social at 3:15 p.m.
Abstract:
One of the most exciting developments in astronomy is the discovery of thousands of planets around stars other than our Sun. But how do these exo-planets form, and why are they so different from those in our own solar system? Which ingredients are available to build them? Thanks to powerful new telescopes, astronomers are starting to address these age-old questions scientifically. Stars and planets are born in the cold and tenuous clouds between the stars in the Milky Way, and the new Atacama Large Millimeter/submillimeter Array (ALMA) now allows us to zoom in on planetary construction zones in nearby disks and determine the physical and chemical structure associated with planet formation. This talk will provide examples of recent work on observations and models of protoplanetary disks in various stages of evolution.
