NICER observation list: Target ID 667702

Abstract

We propose to study thermonuclear X-ray bursts from neutron stars in low mass X-ray binaries using NICER data. The observations will probe the nature of the accretion emission and its response to X-ray bursts. Our primary goal is to derive the fundamental burst parameters such as recurrence time and fuel composition, in addition to understanding the burst-accretion disk interactions. We will examine the bursts in timing as well as spectral domains to probe the nature of burst oscillations along with searching the spectral signature of heavy elements that may form on the neutron star surface. To meet our research goals, the superior spectral and timing resolutions of NICER are key to reveal physical processes at work both in the burst wind and in the impacted accretion disk.
