The X-ray emission of transitional ms pulsars in the disk state is highlypeculiar and is a previously unknown outcome of the disk-magnetosphereinteraction that has yet to be understood. We recently discovered that thetransitional ms pulsar PSR J1023+0038 is also an optical pulsar (Ambrosino,Papitto et al. 2017, Nature Astronomy), strongly suggesting that amagnetospheric rotation-powered process is active. Simultaneous X- ray/opticalhigh-temporal resolution observations are needed to finally nail down themechanism, rotation or accretion power, producing optical and X-ray pulsations.We propose 2x25 ks and 2x30 ks observations of PSR J1023+0038 and 3FGL J1544.61125, simultaneously to high temporal resolution optical observations.

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.
