Description In spite of more than forty years of studies open questions remain on the
structure and physical properties of the emission regions of accreting X-ray
pulsars. Here, we propose to observe the transient X-ray pulsar V0332+53 with
two 20ks pointings during the decline of an outburst with XMM-Newton and NuSTAR.
These joint TOO observations will allow us to observe the source both in high
and low luminosity states when the accretion regime and the emission region are
expected to drastically change. The unique sensitivity and broadband coverage
offered by a simultaneous XMM Newton/NuSTAR observations will allow a detailed
spectral and timing analysis in both states. This is essential to constrain the
properties of the emission region and the critical luminosity.

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.
