|Title||PSR J1023+0038: a tool to investigate the accretion and ejection in LMXBs|
|Author||Dr Sergio Campana|
|Description||PSR J1023+0038 is a binary system that hosts a neutron star and a low-mass, main sequence companion star. It has been observed to switch on timescales of years between states as a radio millisecond pulsar and a LMXB. After its last switch to an X-ray state in 2013, the source has been the object of an extensive multi-wavelength monitoring, during which the switch between three flux X-ray modes (high, low and flare) on timescales of 10 s has been observed. Here we propose a model to account for these switches and ask for the first strictly simultaneous NuSTAR-EPIC-Swift-OM-VLT observation to probe our model using correlations and lags (a profitable tool to probe the emission mechanism), as well as establish differences among the power spectra of the multi-band light curves.|

|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.
