Wilson, Graham Philip (2003) Candidates for historical supernovae and their comparison against known Chinese records. Masters thesis, Durham University.
In this MSc thesis, possible/probable supernova remnants associated with possible/probable historical supernovae are discussed and advancements in knowledge surrounding possible remnants associated with historical supernovae older than about a thousand years are presented. Supernovas in 1006, 1054, 1181, 1572 and 1604 are all discussed for completeness, although these supernovae have been extensively researched and there is little reason to doubt previous work. The historical supernovae of 185, 386, 393 and 837 are all discussed in more detail. In the opinion of the author, supernova of 185 is linked with the remnant 315.3-2.3 in the light of recent research. The supernova of 386 is linked with G11.2-0.3 and a possible record linking G11.2-0.3 with a supernova in 45BC is dismissed. An association of a remnant supernova of 393 remains unsatisfactorily resolved, with CTB37A and CTB37B remaining candidates, and the author has suggested the remnants G343.1-0.7 and G351.7+0.8 as alternatives given a new I-D relation. The age and suitability of GRO/RX J0852 for historical association is discussed, and political reasons for the lack of historical records for an apparent supernova in -1200AD suggested. G292.0+1.8 is discussed as a candidate for a historical supernova and dismissed due to its invisibility in China. The supernova of 837AD is discussed and the link between this and the remnant IC443 remains unconfirmed due to conflicting astrophysical evidence.
