A Search for Expansion and Brightness Changes in the Young Supernova Remnant/Pulsar-Wind Nebula G310.6-1.6
Abstract
Pulsar-wind nebulae (PWNe) are born inside shell supernova remnants (SNRs), and the interaction between PWN and SNR can illuminate each. A new candidate for a PWN/SNR combination, G310.6-1.6, proves to have a classic PWN surrounded at not much larger radius by a very circular, but nonthermal, shell. If the shell is the SNR blast wave, the SNR is very young and the SN was subluminous. But it does not resemble any of the handful of other synchrotron-dominated X-ray shells. We propose to re-observe G310.6-1.6 to search for expansion and brightness changes that should allow an age determination and clarify the nature of the shell. Small-scale structure in the PWN may vary at a detectable level. Our observation could detect a thermal component with as little as 3% of the total flux.
