NICER observation list: Target ID 260901

Abstract

PSR J0726-2612 has been identified as a younger, radio-loud analog to the thermal-X-ray-emitting Magnificent Seven (M7). The emission geometry of PSR J0726, found from absolute X-ray/radio phase alignment, conflicts with that of emission models that include detailed properties of magnetized neutron star atmospheres. Because our X-ray and radio data were taken months apart, we cannot rule out a phase shift from an undetected glitch-like event. With the proposed observations, we will determine the X-ray/radio phase alignment with concurrent radio data; confirm a glitch-like event or else revise the atmosphere models; search for persistent or variable absorption features in the NICER spectrum; and search for timing irregularities and associated spectral changes over a 2-yr timing baseline.
