Fast optical-infrared photometry applied to black hole X-ray binaries has nowrevealed its great potential and has shown to be one of the best ways to probethe jet in its inner most regions. Nonetheless Neutron Star X-ray binaries,which are clearly dominated by the jet at IR wavelength, have not been studiedyet with such approach. Here we propose to observe the Neutron Star Low MassX-ray binary 4U 1728-34 simultaneously with XMM-Newton and HAWK-I@VLT. We ask toperform 6 (7 ks apiece) pointings to be matched by 6 (1 h apiece) HAWK-I@VLTobservations. These data will allow us to study the disc-jet interaction indifferent accretion regimes and to search for, and investigate the between jetproperties in black holes and neutron stars X-ray binaries.

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.
