Abstract
Binary Revelation
Binary star systems that contain a neutron star or a black hole are expected to emit gamma rays. These gamma-ray binaries are a rare class of objects, which are also expected to emit x-rays. Indeed, several such systems were initially detected through their x-ray emission. The
Fermi LAT Collaboration
(p.

; see the Perspective by
Mirabel
) reports the detection of a gamma-ray binary that was previously unknown as an x-ray source. Follow-up observations reveal that the system is also a source of x-rays and that the companion star is a class O star, a type that is very hot and very luminous.
