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 X-Ray telescope and numerous ground based telescopes the team investigated the intriguing source known as LMC P3. One star in the system is tremendously hot
(60,000 degrees F or 33,000 degrees C)! There are tremendous particle winds and also electron winds that produce the varying radiation observed.

Join Tony Darnell and Carol Christian as they discuss with Robin Corbet and Joel Coley (University of Maryland and Goddard Space Flight Center) along with
Malcolm Coe (U of Southhampton) and Laura Chomiuk (Michigan State) their ideas for this investigation, how they found the object and what the observations from multiple observatories tells them about this exotic object.

This Binary system has no heavy metalicity. The mass exchange of this system is still with low metalicirty. Does that help or hinder the possible age of this Binary system. When Malcolm discussed the system he inferred the exchange needed to be symmetric, however there are still problems with the mass exchange, I think. What a FANTASTIC Hangout. Thanks Tony..
