| Description | During AO 18 our team discovered the presence of two IR bursts lagging thermonuclear Type-I X-ray bursts\: this allowed us to put the first constraints on the orbital period of the source 4U 1728-34. Moreover, the profiles of the newly discovered IR bursts showed intriguing .dips. just after the onset of the X-ray bursts. The aim of this proposal is to use the novel method of X-ray-IR burst lag to measure the orbital period of 4U 1728-34 and two other sources, and to quantify the presence of .dips. in their IR reverberation, signatures that would indicate burst-induced changes in the geometry of the accretion flow. We therefore ask to perform 4 (total 56ks) XMM pointings to be matched by 4 (total 14h) HAWK-I@VLT observations of 4U 1728-34, 4U 1705-44 and 4U 1636-53. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
