Millihertz quasi-periodic oscillations detected in an X-ray binary

Astronomers from Australia and Taiwan report the discovery of millihertz quasi-periodic oscillations in a neutron-star low-mass X-ray binary known as 1RXS J180408.9'342058. The discovery, detailed in a paper published September 3 on the arXiv preprint server, could help astronomers better understand the nature and behavior of X-ray binary sources.
