NASA's Kepler Mission: Discovering Strange New Worlds – Dr. William Welsh (San Diego State University)
Saturday 26 October 2013, 7:00pm
William (Bill) Welsh is a Professor of Astronomy at San Diego State University, and a member of NASA's Kepler Mission. He has been very involved in the study of circumbinary planets, and led the discovery of two planets, Kepler-34 and Kepler-35.
"Super" Supernovae and the Quest for the First Stars – Dr. Jeff Cooke (Swinburne University)
Saturday 21 September 2013, 7:00pm – 10:00pm
Very massive stars end their short lives in extremely violent and luminous supernova explosions that can be seen out to great distances. Using a new method, our team has discovered supernovae out to distances much farther than has been previously possible - distances that equate to explosions that occurred 10-12 billion years ago. Several of our discoveries are 10-100 times more luminous than normal supernovae and belong to a rare class of "super-luminous" supernovae. Interestingly, two of these "super-luminous" supernovae may be the first bona-fide examples of a long-theorized third type of supernova explosion believed to have been more common in the early Universe. New surveys now underway will allow us to detect these "super" events all the way back to when the first stars formed after the Big Bang. I will show how we are hot on the trail to discover the deaths of these first stars.
Jeff Cooke is a Research Fellow at Swinburne University in Melbourne, Australia. Previously, he was a McCue Postdoctoral Fellow at the University of California, Irvine and a Postdoctoral Scholar at California Institute of Technology (Caltech). Dr. Cooke received his B.S. in Astronomy at San Diego State University and his M.S. and Ph.D. in Physics at the University of California, San Diego. His work spans a broad range of topics from galaxy formation and evolution, to quasar absorption-line systems, to supernovae. He holds the record for the most distant supernova, a record he continues to break. (http://astronomy.swin.edu.au/~jcooke/).

Are Supernovae Round? – Dr. Douglas Leonard (San Diego State University)
Saturday 13 July 2013, 7:00pm
Douglas Leonard is Associate Professor of Astronomy at San Diego State University, having previously served as National Science Foundation Astronomy and Astrophysics Postdoctoral Scholar at the California Institute of Technology and, prior to that, as a Postdoctoral Fellow with the Five College Astronomy Department in Amherst, MA. Dr. Leonard received his B.A. in astronomy from the University of Pennsylvania, and his M.S., and Ph.D. in astrophysics from the University of California, Berkeley. His publications include over 50 articles in the technical literature. A passionate science educator, his latest endeavors include work on several BBC/Horizon videos on black holes, cosmology, and the deaths of stars (http://www.youtube.com/watch?v=Mx5210jP7yY).
Abstract: Roughly once per century in a typical galaxy, a massive star ends its life in a spectacular explosion called a supernova. The physical process by which these stars explode, however, remains a mystery. Conventional wisdom holds that a spherically symmetric mechanism is at work, one that expels the ejecta equally in all directions. Using recent evidence derived from a novel observational technique employed at the world's largest optical telescopes (including the Hale), I will argue that the innermost regions of these stellar explosions are, in fact, severely distorted, the result of an explosion mechanism that is strongly non-spherical in nature.
Observing and Imaging Our Sun – Jim Lafferty
Saturday 15 June 2013, Solar Observing 12:00 pm, Presentation 2:00 pm
Jim Lafferty hails from Redlands, in Southern California, and has been an amateur astronomer for 35 years. After many years of visual observing, he took on nighttime deep sky imaging. In 2010, he got the solar "bug" and turned from the "dark side" to the adventure that is imaging the Sun. Observing and imaging our nearest star in both traditional "white light" and in the specific band of hydrogen alpha, Jim's work has been featured in Sky and Telescope Magazine, Astronomy Magazine, the UK's "The Astronomer", Amateur Astronomy Magazine, NASA's APOD, Space.com, Yahoo News, numerous blogs and online astronomy sites, and in High School Physics Textbooks. Jim also participates in various public outreach events, as well as giving presentations on the sun in the classroom. He is the author and publisher of the full color hardcover book "Imaging Our Sun" (2012). You can get more information on solar imaging and see more of Jim's work at his website at: http://scopetrader.com/jimlafferty.
For this presentation, Jim will walk us through the basics of observing and imaging the Sun with both hydrogen alpha and white light filtered telescopes. We will discuss the solar features you can expect to see through the eyepiece and some basic info on the best ways to image the sun. Some details on the most common equipment and software will also be discussed.
There will be solar observing at the Outreach Center 12:00 – 5:00pm.
The Search for AM CVn Systems with the Palomar Transient Factory – David Levitan (Caltech)
Saturday 11 May 2013, 7:00 pm
Abstract: Among the most exotic "stars" known are the AM CVn systems - ultra-compact binaries with orbital periods less than an hour. Their extremely short orbital periods make them strong Galactic sources of gravitational waves, but no one has yet understood how many of them exist in the Galaxy. I will describe these systems and why understanding their population is essential, and show how we use the Palomar and Keck telescopes to find new systems and by doing so, better determine their population.
