The 2024 outburst of 1A 1744–361 observed by NICER and Insight-HXMT: Type-I X-ray burst and persistent emission

Open Access

Fig. 8.

Time-resolved spectrum of the burst observed by NICER using the f_a model. This includes the time evolution of the count rate, the blackbody bolometric flux (F_bb), the temperature (kT_bb), the observed radius (R), f_a, and the goodness of fit ( $χ_{v}^{2}$ $\chi_{v}^{2}$ ). The bolometric flux of the blackbody model (F_bb) is in units of 10⁻⁸ erg/cm²/s.
