Selected Works: CHARA Captures Rare Stellar Eclipse

Artist’s depiction of a stellar eclipse
In this artist's concept, Epsilon Aurigae (the supergiant star at right) is starting to be eclipsed by the dust disk circling a single, much dimmer B star. A new model explains the decades-old paradoxes of this system by assuming that its stars are relatively old, not young. Credit: NASA / JPL-Caltech

For the first time ever, scientists working with Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) array have captured very high resolution images that shed new light on what causes the mysterious stellar eclipses of the double star system Epsilon Aurigae.
