Scientific paper

The spin-down power of the 3.82 s pulsar in the SNR CTB 37B is among the largest of magnetars. In addition, its spin-down rate increased by a factor of 2 this year. We propose to continue to monitor its spin-down. Magnetars with the largest spin-down torque are SGRs, and a marked increase in their spin-down rate often precedes an outburst. In this regard, CXOU J171405.7-381031 is very similar to SGR/AXP 1E 1547.0-5408, the magnetar with the largest spin-down power. By analogy with 1E 1547.0-5408, we may be observing the behavior of a magnetar just before it becomes an SGR. Continued study of its spin-down will also enable us to evaluate whether the magnetar can contribute to the TeV emission from HESS J1713-381, in which it resides.
