Scientific paper

The remarkable SNR N157B contains the recently discovered 16 ms pulsar, the most rapidly rotating young pulsar known. In addition to the large-scale diffuse X-ray emission apparently associated with the SNR, three distinct features have been spatially decomposed: the pulsar itself, a surrounding compact wind nebula which is strongly elongated, and a long diffuse trail. We propose Chandra ACIS observations for detailed X-ray spectroscopic measurements of these components. These measurements are necessary for understanding the pulsar emission mechanism, the pulsar wind, and the SNR. In particular, we will test our proposed ram-pressure confined pulsar wind nebula model, which may provide important constraints on the pulsar wind velocity and on the particle acceleration at the shock front.
