NICER observation list: Target ID 261801

Abstract

Following the report of an intense radio flare and MAXI detection of XTE J1810-197 in December 2018, we characterized the magnetar's X-ray outburst properties using a NuSTAR DDT observation. Thus, 15 years after the 2003 discovery of this, the first known transient and radio AXP, it is possible to study the origin and decay of magnetar emission in exquisite detail from the beginning of the outburst in a uniquely accessible source. We propose here to monitor its early X-ray spectral and pulsed evolution, measuring the surface thermal hot spots and magnetic field configuration, and comparing with the original outburst.
