|Title||Is G7.7-3.7 the remnant of a low-luminosity historical supernova in 386 CE|
|Author||Dr Ping Zhou|
|Description||We propose a 72 ks XMM-Newton EPIC observation toward G7.7-3.7, a candidate historical supernova remnant (SNR), with the aim of pinning down its association to the guest star which appeared in 386 CE for 2--4 months. If confirmed, G7.7-3.7 would be one of four historical Type-II SNRs, enlarging the small sample that is used for studying the endpoints of massive stars. G7.7-3.7 may be the only known SNR to be produced from a rare, low-luminosity Type-IIP SN (5% of all Type-II SNe) and is therefore worthy of detailed study. The proposed XMM-Newton observation will greatly improve the accuracy of the SNR-shock age and allow us to study the SNR s properties and search for synchrotron emission.|

|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.
