Abstract	The periastron of the WC5+O9 colliding wind binary WR19 will come in 2017 duringthe XMM-Newton AO-16 phase. WR19 is a massive binary with a 10.1 yr orbitalperiod with a high eccentric orbit. The X-ray spectrum is the best measure ofconditions in the hot postshock gas, and the crucial time for observations isaround periastron passage when densities and emitting volume are changing mostrapidly. We therefore propose 60ksec observation at periastron. By measuring theX-ray luminosity and the column density, we will derive the mass-loss rates ofthese stars that were not measured yet at any other wavelengths.

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.
