Scientific paper

The supernova remnant (SNR) G330.2+1.0 has been recently identified as a nonthermal shell-type SNR in X-rays. Using our Chandra data, we found that the nonthermal X-ray emission of G330.2+1.0 originates primarily from a thin circumferential shell, and discovered a central compact object (CCO) in this SNR. Based on our Chandra results, we propose a 70 ks follow-up XMM observation of this SNR and CCO. Our primary goal is to search for pulsations from the CCO, including a test for the period suggested by Chandra, but only with a marginal significance. The high time resolution and high sensitivity XMM observations are essential to search for the CCO period. We will also perform a spectral analysis of the CCO and SNR, utilizing good photon statisics obtained with XMM.
