Title: Tides: More Than What Floats Your Boat

Author: Robert Morehead

Performers: Robert Morehead & Cameron Hummels

Abstract: Anyone who has spent a day on the beach knows about tides, but this cosmic phenomena is at play throughout the Universe. We'll explore this gravitational tug-o-war and see its effect on the evolution of astronomical systems, from the sandy shores of Earth and ice-covered seas of Europa, to fiery star-skimming exoplants and the delicate dance between galaxies.

Bio: Robert Morehead is a former burger-flipper and science outreach educator who is celebrating the IYA by finishing a B.S. degree in astrophysics at Columbia University. Actually, he will have graduated a week before this podcast airs and will be starting work on a PhD. at the University of Florida in the fall. While at Columbia he has worked on a robotic telescope for lunar observations and modeled tidal evolution in exoplanet systems. He plans to continue working on exoplanets in grad school. His hobbies are numerous and all of them are extremely nerdy.
