Abstract

We use the star formation history map of the Large Magellanic Cloud recently published by Harris & Zaritsky to study the sites of the four smallest (and presumably youngest) Type la supernova remnants: 0509-67.5, 0519-69.0, N103B and DEM L71. We find that three of the four Type la remnants are associated with old, metal-poor stellar populations, with little or no recent star formation. These include SNR 0509-67.5 which is known to have been originated by an extremely bright SN 1991 T-like event, and yet is located very far away from any star forming regions. It is very unlikely that this bright Type la SN had a young stellar progenitor The fourth Type la remnant, SNR N103B is associated with vigorous star formation activity in the last 100 Myr, and might have had a relatively younger and more massive progenitor.
