We present a new Chandra observation of supernova remnant (SNR) G350.1-0.3.The high resolution X-ray data reveal previously unresolved filamentarystructures and allow us to perform detailed spectroscopy in the diffuse regionsof this SNR. Spectral analysis demonstrates that the region of brightestemission is dominated by hot, metal-rich ejecta while the ambient materialalong the perimeter of the ejecta region and throughout the remnant's westernhalf is mostly low-temperature, shocked interstellar/circumstellar medium(ISM/CSM) with solar-type composition. The data reveal that the emissionextends far to the west of the ejecta region and imply a lower limit of 6.6 pcon the diameter of the source (at a distance of 4.5 kpc). We show thatG350.1-0.3 is likely in the free expansion (ejecta-dominated) stage andcalculate an age of 600-1200 years. The derived relationship between the shockvelocity and the electron/proton temperature ratio is found to be entirelyconsistent with that of other SNRs. We perform spectral fits on the X-raysource XMMU J172054.5-372652, a candidate central compact object (CCO), andfind that its spectral properties fall within the typical range of other CCOs.We also present archival 24 um data of G350.1-0.3 taken with the Spitzer SpaceTelescope during the MIPSGAL galactic survey and find that the infrared andX-ray morphologies are well-correlated. These results help to explain thisremnant's peculiar asymmetries and shed new light on its dynamics andevolution.
