End point of the rp process on accreting neutron stars
Schatz, H.; Aprahamian, A.; Bildsten, L.; Cumming, A.; Ouellette, M.; Rauscher, T.; Thielemann, Friedrich-Karl; Wiescher, M. (2001-04-16)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 ... -
The endpoint of the rp-process on accreting neutron stars
Schatz, H.; Aprahamian, A.; Bildsten, L.; Cumming, A.; Ouellette, M.; Rauscher, T.; Thielemann, Friedrich-Karl; Wiescher, M. (2001-05-21)We find that the rp process in X-ray bursts and in steady state burning, for example in X-ray pulsars, ends in a SnSbTe cycle. We discuss the consequences for the neutron star crust composition an X-ray burst light curves. -
Models for Type I X-ray bursts with improved nuclear physics
Woosley, S.E.; Heger, A.; Cumming, A.; Hoffman, R. D.; Pruet, J.; Rauscher, T.; Fisker, J. L.; Schatz, H.; Brown, B.A.; Wiescher, M. (2004-03)Multizone models of Type I X-ray bursts are presented that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, for energy generation and include the most recent measurements and estimates ...
