NICER observation list: Target ID 365702

Abstract

We propose NICER observations of low mass X-ray binaries, 4U 1608-52, Aql X-1, and 4U 1735-44 that show thermonuclear X-ray bursts, for 80~ks each. NICER provides the largest effective area in the soft X-rays, which allow for time resolved spectral and temporal analysis of the evolution of bursts. Initial observations of these events in the soft X-rays, showed that unlike the previous assumption time resolved X-ray spectra of X-ray bursts often can not be fit with simple Planckian functions and often require a second component whose nature is not really understood well yet, although assumed to be due to reflection off the accretion disk. We plan to observe sources with relatively low hydrogen column density to fully investigate their soft components.
