SUMMARY:General Meeting – September 2026
DESCRIPTION: Join Zoom\n\nFree and open to the public held both inperson and online.\nWe have a new inperson location\, “OCC Lecture Halls 1&2” of the “Orange Coast College\,” next to the planetarium. Click here for parking instructions and more information. \nThe main speaker at this meeting will be joining us live from Pasadena\, California. \n  \nSounds of the Stars:\n  \nJourney to the Center of a Star\n  \n \nWhat lies at the center of a star? A stellar core is surrounded by a million Earth’s worth of plasma\, so we cannot see it directly. However\, the immense power of a star’s radiation causes nearly all stars to pulsate\, creating “star quakes” at their surfaces. These oscillations are a collection of musical notes that uniquely define each star and are determined by its internal structure\, just as the sound of a musical instrument is determined by its size and shape. Join me for a cosmic symphony as we journey to the center of the Sun\, Saturn\, white dwarfs\, red giants\, and heartbeat stars. \n \nJim Fuller is a professor of theoretical astrophysics at the California Institute of Technology. His research covers a broad array of topics\, ranging from Saturn’s moons to massive stars that explode as supernovae or collapse into black holes! Recently he has been studying the evolution of massive stars just before supernova\, the neutron stars and black holes that they produce\, asteroseismology and magnetic fields inside of red giants\, pulsations of tidally distorted stars\, the deep interior of Saturn as revealed by its rings\, and the long-term orbital evolution of exoplanets and moons. \n\nViews: 4

SUMMARY:General Meeting – October 2026
DESCRIPTION: Join Zoom\n\nFree and open to the public held both inperson and online.\nWe have a new inperson location\, “OCC Lecture Halls 1&2” of the “Orange Coast College\,” next to the planetarium. Click here for parking instructions and more information. \nThe main speaker at this meeting will be joining us inperson. \n  \nHow to Image an Exoplanet\n  \n  \nA little look under the hood of the Gemini Planet Imager 2.0 instrument\, which will directly image young Jovian exoplanets. \n  \nOver the past 30 years\, astronomers have discovered thousands of planets beyond our Solar System. Yet only a tiny fraction have ever been directly imaged. The challenge: planets are extremely faint compared with their host stars\, and appear very close beside them in the sky. Astronomers have developed cutting-edge instruments to overcome this challenge. This talk will explain how techniques such as adaptive optics and coronagraphs allow us to reveal these hidden worlds\, what we can learn from them\, and how the next generation of telescopes will bring us closer to directly imaging planets like Earth. \n \nSaavidra Perera is an adaptive optics scientist at the California Institute for Technology working in the field of astronomical instrumentation. Her work focuses on overcoming the limitations of the Earth’s atmosphere on ground-based visible/infrared astronomy. \n  \n\nViews: 4
