O-rich supernova remnants (SNRs) provide an excellent opportunity for the study of core-collapse (CC) nucleosynthesis and the late-stage evolution of a massive star. While young O-rich SNRs (e.g., Cas A and G292.0+1.8) are being extensively studied, such studies are intrinsically limited because the early-stage of the blast wave and reverse shock may not reveal the full nature of metal-rich ejecta and the surroundings. Studies of relatively old O-rich SNRs are essential for a comprehensive understanding of CC SNRs, complementing those of young SNRs. The old O-rich SNR 0049-73.6 is a perfect example for such a study, revealing both high- and low-Z ejecta and well-evolved blast wave. Thus, we propose a deep 450 ks ACIS observation of 0049-73.6 for a detailed X-ray imaging spectroscopy.
