We propose XMM-Newton observations of two hard X--ray transients containing fastspinning and/or high magnetic field neutron stars to probe their quiescentemission. Due to their faintness these sources are likely in a regime which doesnot allow matter to fall directly onto the neutron star surface (propellerstate). The proposed observations will allow us to study 4U 0115+63 and V0332+53at the deepest levels ever observed for this class of sources to shed light onthe physics of the disk-magnetosphere interaction and on the heating of themagnetic polar caps in the high magnetic field regime.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
