  • Description: We discuss in this Letter the association of the candidate magnetar CXOU J171405.7-381031 with the supernova remnant CTB 37B. The recent detection of the period derivative of the object allowed an estimation of a young characteristic age of only \(\sim 1000 yr\). This value is too small to be compatible even with the minimum radius of the remnant \(\geq 10 pc\), the value corresponding to the {\it lower} limit of the estimated distance of \(10.2 \pm 3.5 kpc\), unless the true distance happens to be even smaller than the lower limit. We argue that a consistent scenario for the remnant origin, in which the latter is powered by the energy injected by a young magnetar, is indeed more accurate to explain the young age, and points out to its non-standard (i.e. magnetar-driven) nature.
