NICER observation list: Target ID 467203

Abstract

zeta Pup is a well-studied, archetypal O-type supergiant with more than one period of cyclical variability detected in multiwavelength studies. Previous Chandra and XMM-Newton observations have shown the presence of a 1.78-d period, believed to be linked to rotation, and another, longer unexplained period of around 5-6d. Monitoring this star with NICER using two separate observing cadences, we seek to probe both signals and their coherence timescales, as well as constrain the presence of possible additional stochastic variability. By combining this dataset with simultaneous BRITE space-based optical photometry, we will trace these signals back to the wind structures -- both large-scale and possibly small-scale -- that cause them, and gain a deeper understanding of the outflows of OB stars.
