Monday 30 Apr 2018[Seminar] The CHARA Array and the Exciting Science of Submilliarcsecond Astronomy

Dr. Jeremy Jones - Georgia State University

Physics 4th Floor 14:00-15:00

The flagship Array of the Center for High Angular Resolution Astronomy (CHARA) provides submilliarcsecond resolution in the optical and near-infrared. The CHARA Array consists of six telescopes which are spread out over 300 meters and linked together as an interferometer allowing for such high resolution. The Array has been used in the study of a variety of topics in stellar astronomy, including measuring stellar angular diameters, imaging stellar shapes and surface features, mapping the orbits of close binary companions, and resolving circumstellar environments. I will show highlights of the exciting science that has been done with the Array and discuss my own research into rapidly rotating A-type stars.
