Description | In the past two years, three pulsar binaries have shown surprising back-and-forth transitions between an accreting low mass X-ray binary (LMXB) state and a non- accreting radio millisecond pulsar (MSP) state. These transitional MSPs (tMSPs) overturned the idea that accretion in an LMXB switches off permanently in a single occurence during pulsar .recycling., but it is unclear how/why the transitions happen. PSR J2339-0533 is a likely tMSP with spin and orbit parameters very similar to the known tMSPs and shows signs of intermittent accretion, orbital period and lightcurve variations. These signs suggest that PSR J2339-0533 may imminently transition into an LMXB. With 150ks NuSTAR and 100ks XMM observations, we propose to establish the pre-transition properties, critical for future work. |

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. |
