Description

This study examines the observational signatures of optically thick winds in thermonuclear X-ray bursts (XRBs). By combining the wind models from Herrera et al. (2023) with the burst models from José et al. (2010), we reconstruct theoretical X-ray light-curves and effective temperature evolution. Using the HEASOFT package, we simulate observational counterparts of said theoretical predictions, as well as time-resolved spectra, for the NASA X-ray telescope on board the ISS, NICER (Nuclear star Interior Composition ExploreR) and for NewAthena. This research enhances understanding of radiative winds in XRBs and provides a framework for future observational assessments.
