| Description | Three years ago, PSR J1023+0038 (J1023) transformed from a rotation-powered millisecond pulsar state to an accretion-disk-dominated X-ray pulsar state. In this state it shows coherent X-ray pulsations indicating active accretion at low luminosities. Using these pulsations we have discovered that in the X-ray state J1023 is spinning down 27% faster than the radio state (Jaodand et al. 2016). Along with this unique, long-term X-ray timing solution for a transitional millisecond pulsar (tMSP) we also find a change in average orbital period derivative between states. Extending the span of our timing solution to a possible J1023 transition (back to radio) in the coming year(s) is critical to understand tMSP transitions and accretion physics. |

| 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. |
