Afternoon Astronomy Coffee Hangout on 10 November

“A Gamma Ray Binary in Another Galaxy: A massive star paired with a crushed stellar core remnant" Afternoon Astronomy Coffee Hangout

A search for binary stars that emit gamma-rays using NASA’s Fermi satellite turned up a luminous object in another galaxy. These objects are characteristically variable. Using additional telescopes including the Swift Gamma Ray Burst Mission and numerous ground based telescopes the team investigated the intriguing source known as LMC P3. One star in the system is incredibly hot — 60,000°F or 33,000°C! There are tremendous particle winds and also electron winds that produce the varying radiation observed.

Join Tony Darnell and Carol Christian on Thursday, 10 November, at 3:00 pm ET as they chat with Robin Corbet (University of Maryland, Baltimore County), Joel Coley (Goddard Space Flight Center), Malcolm Coe (University of Southampton), and Laura Chomiuk (Michigan State) about their ideas for this investigation, how they found the object, and what the observations from multiple observatories tells them about this exotic object. The best place to hangout with us will be on YouTube, broadcast on the Deep Astronomy Channel. You can also take part in the live chat, tune in via the on Deep Astronomy Facebook page, and join the conversation on Twitter with #AstroCoffee. Archives of previous hangouts in this series may be found in a Deep Astronomy YouTube playlist.

What Are Afternoon Astronomy Coffee and Future in Space Hangouts?

Future In Space” and "Afternoon Astronomy Coffee" Hangouts are part of a weekly series, held every Thursday, that also includes a segment on Footsteps to Mars. We bring the the latest research in astronomy, highlights from the future of space astronomy and astronautics planning, as well as updates on the exploration of Mars to you every week via Hangouts on Air. With the cooperation of both the American Astronomical Society (AAS) and the American Astronautical Society (the other AAS), our hosts Tony Darnell, Carol Christian, Alberto Conti, and Harley Thronson bring you topics that examine today's breakthroughs in research and look forward to peer into the unfolding possibilities of what we may learn about the universe and Mars exploration. We join with members of the American Astronomical Society to chat, in an informal online setting modeled after "science coffee" events held in universities and research organizations across the country. We will examine what we hope to learn about exoplanets, black holes, the early universe, quasars, and life in the universe along with what technologies might help us — and reflect upon the scientific endeavors occurring today that uncover amazing astrophysics and lay the groundwork for studies to come.

We will also explore the technology and engineering used today as well as possibilities for future space travel and research with members of both Societies, and probe what our future in space may look like and how we might get there. We will examine the underlying technologies of space telescopes, orbiters, landers, and human space vehicles now and in the years to come. We will delve into topics that help us understand the possibilities and limitations of human space flight and eventual human colonization of other worlds.

We hope you can join us each month as we bring experts from both Societies — people who think about and plan for our future in space — to your computer, tablet, or smartphone. We invite you to bring your questions and comments and get ready to learn about the amazing possibilities for the future of space astronomy and exploration.
