Title:  A Tale of Epsilon Eridani – How Debris Disks Tell Us about Exoplanetary Systems

Presenter:  Dr. Kate Su, astronomer from Steward Observatory

Epsilon Eridani, a young solar-like star—at a distance of 10.5 light years from the Sun—is one of the closest stars with a planetary system. Dr. Su’s talk will focus on how astronomers use the emission from orbiting dust to reveal the underlying planetary architecture of Epsilon Eridani. Her main research—with the goal of understanding the origin and evolution of our own solar system—involves interpreting data obtained from ground-based telescopes around the globe, as well as from space telescopes and the airborne observatory SOFIA.
