Paul Robertson, associate professor of physics and astronomy at the University of California, Irvine, is co-author of a new paper in The Astronomical Journal on an exoplanet that is tantalizingly close to Earth. The proximity of this exoplanet helps astronomers glean more details about it. They want to know how it compares in size to Earth, if it has an atmosphere, and if it is in the habitable zone, a distance from the host star that would make it possible for the planet to have liquid water on its surface, a key ingredient to support potential life. In this episode of the UC Irvine Podcast, Robertson discusses the tools he and his team used to characterize this exoplanet and what he hopes to learn in future exoplanet hunting efforts.
