| Description | The temporary disappearance of radio emission from a pulsar is known as .nulling. The nature of nulling is not fully understood yet, but it is considered as evidence of turning off the magnetospheric activity. A changed magnetospheric activity can affect the pulsar.s X-ray emission too, in particular if these changes persist for some time. Nulling pulsars are usually too faint in X-rays to detect emission disappearance in the typically short nulling intervals. The nearby isolated PSR B1706-16 shows sufficiently long nulling intervals and may be X-ray bright enough to explore the nulling phenomenon in X-rays for the first time. The proposed short observations will establish the X-ray properties needed for planning a longer follow-up observation. |

| 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. |
