Sensitivity Study of Type-I X-ray Burst To Nuclear Reaction Rates*

Neutron stars in low-mass X-ray binaries, where they can accrete hydrogen-rich or helium-rich materials onto their surfaces, frequently exhibit intense thermonuclear flashes called Type-I X-ray bursts (XRBs). XRBs are powered by the triple-α process, the αp process, and the rapid proton capture process. These different nucleosynthesis processes that drive the event plays a vital role in accurately comparing theoretical models and observations. In our study, we examine

the impact of uncertainties in these nuclear reactions using the ONEZONE model (Cyburt et al., 2016) with different compositions of the accreted material from the companion star. We perform the sensitivity of our X-ray burst model by varying proton and alpha-induced reaction rates in JINA REACLIBV2.2 within representative nuclear physics uncertainties. I will discuss the impact of nuclear reactions on the X-ray burst light curve and ash production.
