We calculate the rapid proton (rp) capture process of hydrogen burning on the surface of an accreting neutron star with an updated reaction network that extends up to Xe, far beyond previous work. In both steady-state nuclear burning appropriate for rapidly accreting neutron stars (such as the magnetic polar caps of accreting x-ray pulsars) and unstable burning of type I x-ray bursts, we find that the rp process ends in a closed SnSbTe cycle. This prevents the synthesis of elements heavier than… Expand

Nucleosynthesis of proton rich nuclei on accreting neutron stars related to type I X-ray burst
Abstract Using a shell flash model, we have investigated the relation between the endpoint of the rp-process and the ignition pressure. We have found a striking feature of the rp-process during theExpand
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
Electron capture reactions in neutron star crusts: Deep heating and observational constraints
We compute the nucleosynthesis in the outer crust of an accreting neutron star, starting with an rp-process distribution of nuclei and integrating to neutron-drip density. Our reaction networkExpand
Final products of the rp-process on accreting neutron stars
Using both shell-flash and realistic models on accreting neutron stars with the full nuclear reaction network up to Bi, we investigate the detailed relation between the final products of theExpand
Superbursts: A New Probe of the rp-Process
Long term monitoring of X-ray burst sources has discovered a new class of thermonuclear X-ray bursts from accreting neutron stars in low mass X-ray binaries. These “superbursts” have durations andExpand
Decay studies at the end of the rp-process
The rapid proton-capture process (rp-process) produces proton rich nuclei on the surface of accreting neutron stars. The light curves of type I X-ray bursts are an observable result of the energyExpand
Thermal state of transiently accreting neutron stars
We study thermal states of transiently accreting neutron stars (with mean accretion rates u M ∼ 10 −14 −10 −9 Myr −1 ) determined by the deep crustal heating of accreted matter sinking into stellarExpand
From Exploding Stars to the Laboratory: Nucleosynthesis in the rp-Process
The rp-process is thought to result from explosive stellar conditions of high temperature and density typically in an accreting binary star system. These conditions favor the successive protonExpand
Radioactive nuclei on accreting neutron stars
With new data from RXTE, Chandra, and XMM X-ray astronomy of accreting neutron stars enters a precision era. Precision nuclear physics from experiments with radioactive beams is needed to interpretExpand
Experimental Challenge to Heavy Element Synthesis under Explosive Burning on Neutron Stars
Binary stellar systems that involve a neutron star or two neutron stars make interesting phenomena, X-ray bursts and kilo-novae, respectively, which involve explosive burning either in theExpand
