Description Pulsar inner gaps are the engines to power radio and high energy emissions. There are two types of gaps, i.e, the vacuum gap and the space-charge-limited flow gap, and different models predict different levels of polar cap heating. Models can be then tested by observing thermal emission due to polar cap heating from relative slow, old pulsars where this component dominates the spectra. Our target is the famous 1.1s drifting pulsar PSR B0943+10. Its clear drifting pattern supports the vacuum gap model, and refers to a thermal X-ray luminosity of over 1% of the spindown luminosity of the pulsar. We propose a 35 ks observation to this pulsar to detect the polar cap heating thermal emission, which would have profound implications to pulsar inner gap theories.

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.
