According to the current paradigm, accretion onto black holes and neutron starsis associated with two types of outflows that are mutually exclusive. At >E-2 ofthe Eddington limit, disk winds are detected through narrow X-ray absorptionfeatures, whereas at lower mass-accretion rates radio jets are seen. However,our AO1 NuSTAR observation of the neutron star low-mass X-ray binary IGRJ17062-6143 revealed a virgul3-4 sigma narrow absorption line at virgul6.85 keV. Thisprovides the very first evidence that disk winds can be launched at merely virgulE-3of Eddington, and may co-exist with a radio jet. We propose for a 75 ks NuSTARobservation and a supporting 70 ks XMM observation to solidify this measurement,which would change our current views of inflow-outflow coupling in accreting compact objects.

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.
