NICER observation list: Target ID 463401

The puzzling variety of orbital phase locked X-ray flares and super-orbital modulations in the Supergiant Fast X-ray Transient (SFXT) IGR J16479-4514 indicates the presence of stable large scale structures in the stellar wind of the supergiant star. To investigate these structures in the stellar wind, we propose 25 kilosec observations of IGR J16479-4514 each at two orbital phase 0.3 and 0.7 (50 kilosec total), where these X-ray flares occur. The time of observations will be matched to the super-orbital maximum phase, where many of these X-ray bright flares are coincident. The results from hardness ratio and spectral analysis during the rise and decay of these flares will be used to constrain stellar wind models predicting the existence of these large scale structures in the wind.
