| Abstract | In 2013, PSR J1023+0038 transformed from a rotation-powered radio millisecondpulsar state to an accretion-disk-dominated X-ray pulsar state, where it hasremained since. In its current state it shows coherent X-ray pulsations at lowluminosities (~10^33 erg/s). Using XMM-Newton we have found that in the diskstate the pulsar is spinning down measurably faster compared to the radio-loudstate. This first of its kind long-term X-ray timing solution for anaccreting/transitional millisecond pulsar (tMSP) has helped us place usefulconstrains on models for disk-magnetosphere interaction. We propose to extendthe current timing solution with XMM-Newton through an impending J1023 statetransition in the near future, in order to constrain accretion models. |

| 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. |
