Systematic study of the composition of Type I X-ray burst ashes: Neutron star structure v.s. Reaction rate uncertainties
Guoqing Zhen, Helei Liu, Akira Dohi +4
In this study, we calculate for the first time the impacts of neutron star(NS) structure on the type I X-ray burst ashes using the \texttt{MESA} code. We find an increased mass fra…

The double-peaked type I X-ray bursts with different mass accretion rate and fuel composition
Liyu Song, Helei Liu, Chunhua Zhu +3
Using the MESA code, we have carried out a detailed survey of the available parameter space for the double-peaked type I X-ray bursts. We find that the double-peaked structure appe…

The Impacts of Neutron-Star Structure and Base Heating on Type I X-Ray Bursts and Code Comparison
Guoqing Zhen, Guoliang Lv, Helei Liu +6
Type I X-ray bursts are rapidly brightening phenomena triggered by thermonuclear burning on accreting layer of a neutron star (NS). The light curves represent the physical properti…
