Abstract
We propose to observe a newly identified supernova remnant (SNR) G308.3-1.4 and its associated compact X-ray object with ATCA. While the X-ray observation can confirm the SNR nature, it does not provide information for the distance which is a key parameter in determining the physical properties of the SNR (e.g. age). We therefore propose a high resolution spectral line observation for estimating the SNR distance as well as search for the evidence for the possible SNR-molecular cloud interaction. For the compact X-ray object, we have discovered a 1.4 hrs periodicity. Together with its X-ray and optical spectral properties, this object suggests a possible evidence for a compact binary survived in a SN explosion. For constraining its nature, we also propose a high angular resolution continuum observation with ATCA for searching radio point source at its X-ray position as well as other region of G308.3-1.4.
