| Description | We have identified a central compact object (CCO) in the newly identified supernova remnant G308.3-1.4. An interesting periodicity candidate of 1.4 hours has been found in a short exposure by Chandra. Together with its flux variability, this object resembles the well-known CCO associated with RCW 103. However, different from the case in RCW 103, optical/IR counterpart of the CCO in G308.3-1.4 is unambiguously identified and its spectral energy distribution suggests it as a promising compact binary candidate. We propose a XMM-Newton observation to confirm the nature of this object so as to search for the direct evidence of a compact binary survived in a supernova. |

| 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. |
