NICER observation list: Target ID 671304

Abstract

The Magnificent 7 (M7) are seven slowly-rotating, highly magnetized isolated neutron stars with thermal X-ray emission, six of which have X-ray pulsations. Their nearly-pure thermal spectra, along with absorption features detected in most of the M7, provide insight into their atmospheric composition and magnetic and emission geometries. The thermal emission also provides a unique probe of the neutron star equation of state. All but one of the M7 have been observed with NICER, and we propose to complete this dataset. In light of recent results suggesting that many of the M7 may display timing and spectral variability, we additionally propose to monitor a subset of these sources to search for variability in more of these sources.
