Description Periodically pulsed X-ray emission from the nearby B2 star Rho Oph A have been discovered along with a variable magnetic field and strongly modulated radio emission. All these observations fit in a model of an oblique magnetic rotator, where, alternatively, the magnetic poles and their radio emission point towards the Earth. In this proposal we request to use NuSTAR and XMM-Newton to monitor Rho Oph A for about two rotational periods (total exposure virgul140 ks) in order to clarify the link between X-rays, radio emission and magnetism which requires us to firmly characterize its high energy (> 10 keV) emission. The hard X-ray spectrum will provide a clear signature of non-thermal emission and a better knowledge of the auroral emission and particle acceleration in magnetic B stars.

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.
