Imaging Stars: A Century of Advances in High Angular Resolution Astronomy

Tuesday, January 7, 2020

10:00 - 11:30 AM

Hawaii Convention Center


On the night of December 13, 1920, Albert Michelson and Francis Pease became the first to measure the size of a star other than the Sun. This remarkable feat was accomplished using a 20-foot beam interferometer mounted on the 100-inch Hooker telescope at Mount Wilson Observatory. Their technique has blossomed into the field of long baseline interferometry that has made possible the resolution of stars hundreds of times smaller than the first target Betelgeuse. These new measurements are pushing stellar astrophysics into a new realm of precision to explore stellar evolution. In celebration of this historic achievement, we will bring together a series of talks to highlight recent advances in resolving stars at milli-arcsecond resolution across different evolutionary stages.

There will be an associated poster session.  If you are interested in contributing a research poster, please select the special session title, "Imaging Stars: A Century of Advances in High Angular Resolution Astronomy" when submitting the abstract for your poster.
