Dependable predictions of the X-ray burst ashes and light curves require a stringent constraint on the composition of the accreted material as an input parameter. Lower metallicity models are generally based on a metal deficient donor and all metals are summed up in CNO abundances or solar metal distribution is assumed. In this work, we study the alteration of accreted composition due to spallation in the atmosphere of accreting neutron stars considering a cascading destruction process. We find… Expand

The Radius of PSR J0740+6620 from NICER and XMM-Newton Data
PSR J0740+6620 has a gravitational mass of 2.08 ± 0.07 M ⊙, which is the highest reliably determined mass of any neutron star. As a result, a measurement of its radius will provide unique insightExpand
Constraining the Neutron Star Mass–Radius Relation and Dense Matter Equation of State with NICER. III. Model Description and Verification of Parameter Estimation Codes

Carbon Flashes in the Heavy-Element Ocean on Accreting Neutron Stars
We show that the burning of a small mass fraction X12 of 12C in a neutron star ocean is thermally unstable at low accumulated masses when the ocean contains heavy ashes from the hydrogen-burningExpand
Hydrodynamic Models of Type I X-Ray Bursts: Metallicity Effects
Type I X-ray bursts (XRBs) are thermonuclear stellar explosions driven by charged-particle reactions. In the regime for combined H/He-ignition, the main nuclear flow is dominated by the rp-processExpand
Constraints on Bygone Nucleosynthesis of Accreting Neutron Stars
Nuclear burning near the surface of an accreting neutron star produces ashes that, when compressed deeper by further accretion, alter the star's thermal and compositional structure. BygoneExpand
