Description | We propose the first useful focusing X-ray observations of PSR J1734-3333, a possible magnetar progenitor. This source, a 1.2 s radio pulsar, has inferred magnetic field 5.2x10^13 G, above the quantum critical field and close to those of magnetars. In observations made over 10 yr, we have measured a braking index for this source, n=1.3715+/-0.0077. So low a braking index is unprecedented and suggests magnetic field growth: this source may soon become, or is already, some form of magnetar. The requested short observation could detect anomalous X-ray emission from this object and complete the hypothesized evolutionary chain between high-B rotation-powered pulsars and magnetars. |

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. |
