Physics

Scientific paper

Imaging is now a reality at the CHARA interferometer (Mt. Wilson, CA) using the newly-commissioned Michigan Infrared Combiner (MIRC). In this talk, I will review our recent progress and give an overview of the transformative science possible with <1; milli-arcsecond angular resolution in the near-infrared. With the new facilities, main-sequence stars beyond the Sun have been imaged for the first time, and we reveal remarkable new views of the centrifugally-distorted and gravity-darkened photospheres of nearby "rapid rotators." Imaging is also an essential tool for probing the physics of complex time-variable systems, such as interacting binaries and circumstellar disks. I will show how the CHARA Array can now give us fresh insight into well-known prototype systems.
