Craig Heinke
Globular Clusters and Their Weird Binary Stars

Globular clusters are old, dense conglomerations of stars, which are also unique physical laboratories. The denser globular clusters have stars packed so tightly together that stars occasionally collide with each other. More often, binary stars (pairs of stars orbiting around each other) have their orbits disrupted by other stars, leading to the replacement of one star in the binary with the intruder star and the formation of unusual binaries. Binaries including extremely dense dead stars, like neutron stars or black holes, can produce X-ray binaries, where the dense star steals mass from its companion. As the matter spirals down from the companion to the dead star, it heats up to millions of degrees and emits X-rays, permitting us to study these exotic systems.

7:30 PM Guest Speaker

R.A. Rosenfeld
Music of the Spheres: Astronomers as Musicians & Musicians as Astronomers

The interrelationship between music and astronomy goes back at least as far as cosmologies of the 6th century BC, orderings of knowledge, and educational norms in the “west”. Stronger in some periods than others, stranger in its details, and occasionally entertaining in its manifestations, the relationship has never entirely attenuated. This talk will introduce the theoretical underpinnings, the cultural practices, and some of the astronomers who made music, and the musicians who did astronomy. The talk will be illustrated with live musical examples.

Alex Filippenko
Dark Energy and the Runaway Universe

We expected the attractive force of gravity to slow down the rate at which the Universe is expanding. But observations of very distant exploding stars (supernovae) show that the expansion rate is actually speeding up, an amazing discovery that was honored with the 2011 Nobel Prize in Physics to the teams’ leaders and the 2015 Breakthrough Prize in Fundamental Physics to all team members. Over the largest distances, the Universe seems to be dominated by a mysterious, repulsive “dark energy” that stretches space itself faster and faster. But the physical origin and nature of dark energy, which makes up about 70% of the contents of the Universe, is probably the most important unsolved problem in all of physics; it may provide clues to a unified quantum theory of gravity.

Sharon Morsink
100 Years of Einstein’s General Theory of Relativity

One hundred years ago, Einstein published his general theory of relativity, essentially a set of equations describing very strong gravitational fields. This set of abstract equations is so complicated that Einstein didn’t think it was possible to solve them! Over the last century we have learned how to solve the equations and how to apply them to many astronomical observations such black holes, gravitational lenses and the Universe. In this talk, we’ll  look at some of the cool images of these legacies of Einstein.
