Description
Type-I X-ray bursts are rapidly brightening phenomena triggered by the nuclear burning of light elements near the surface of accreting neutron stars. Observed light curves are sensitive to many model parameters. We focus on the uncertainties of the nuclear equation of states, which determines the mass and radius of neutron stars. Regarding the observations, we focus on one of the regular bursters, 1RXS J180408.9-342058, where two series of X-ray bursts have been detected by NuStar. Based on our numerical models covering whole areas of neutron stars, we will discuss the possibility of constraining the equation of states and the mass from the observed recurrence time and persistent flux.
