Modeling x-Ray bursts with New Nuclear Physics

Multi-zone x-ray burst models simulate thermonuclear explosions on the surface of accreting neutron stars. The underlying nuclear reaction sequence in the x-Ray burst is the rp-process. We used an updated nuclear reaction network, in which we updated mostly rp-process reactions, in a one-zone model and observe its impact on x-Ray bursts, using the x-Ray light curve and final produced ashes. We also explored the validity of one-zone approximations as tools to investigate nuclear physics by comparing to a full 1D multi-zone model.
