摘要：

We present an infrared study of supernova remnants using the AKARI IRC Survey of the Large Magellanic Cloud as well as a preliminary result of follow-up near-infrared spectroscopic observations by AKARI The AKARI LMC survey covered about 10 square-degree of the LMC including 21 SNRs, a half of the known SNRs. Among those, we found that 8 SNRs have distinguishable infrared emission in NIR and/or MIR bands. We explore the statistical properties of their infrared colors and discuss the origin of the infrared emission. For the further analysis, we have performed NIR spectroscopic observations on four NIB. bright LMC SNRs during the AKARI warm phase. We examined their NIR spectra and identified strong hydrogen recombination lines with several H-2 molecular lines in most SNRs. We discuss their implications for the SNRs with their environment and the nature of the IR emission.
