Abstract	The wind-wind collision (WWC) in eccentric massive binary systems producespredictably variable X-ray plasma. This nearly controlled collision providesan ideal laboratory for shock astrophysics, providing key constraints on how gasthermalizes at variable density and on particle acceleration. Joint XMM-Newtonand NuSTAR observation of WR 140 in AO14 discovered an extremely hard X-raycomponent, which can originate either from a kT ~13 keV plasma or inverseCompton scattering. WR 140 will experience its periastron passage in 2016, acritical time when the WWC emission changes dramatically. We propose jointXMM-Newton/NuSTAR observations of WR 140 at key phases around periastron inAO15, to determine the origin of this component and understand the X-ray Minimum.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
