|Title||Unveil accretion onset mechanisms of a normal outburst of EXO 2030+375|
|Author||Dr Carlo Ferrigno|
|Description||We propose to observe the Be-X-ray binary system EXO 2030+375 during its periastron passage for 30 ks to study the onset of the accretion activity. Accretion disc instability at the border of the magnetosphere have been evidenced by quasi-periodic hour-long flux oscillations detected during INTEGRAL serendipitous observations in 2011 and by EXOSAT in 1985. Existing RXTE snapshots observations during past outbursts are unable to characterise the way in which matter begins to penetrate into the magnetosphere. The unprecedented sensitivity of XMM-Newton and its continuous coverage will allow us to investigate in detail the opening of the magnetic gate for this high-magnetic field neutron star.|

|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.
