Nuclear pasta and supernova neutrinos at late times
C. J. Horowitz, D. K. Berry, M. E. Caplan +5
Nuclear pasta, with nucleons arranged into tubes, sheets, or other complex shapes, is expected in core collapse supernovae (SNe) at just below nuclear density. We calculate the add…
Neutrino-nucleon scattering in supernova matter from the virial expansion
C. J. Horowitz, O. L. Caballero, Zidu Lin +2
We generalize our virial approach to study the neutral current neutrino response of nuclear matter at low densities. In the long-wavelength limit, the virial expansion makes model-…
A lower limit on the heat capacity of the neutron star core
Andrew Cumming, Edward F. Brown, Farrukh J. Fattoyev +3
We show that observations of the core temperature of transiently-accreting neutron stars combined with observations of an accretion outburst give a lower limit to the neutron star…
Astromaterial Science and Nuclear Pasta
M. E. Caplan, C. J. Horowitz
We define `astromaterial science' as the study of materials in astronomical objects that are qualitatively denser than materials on earth. Astromaterials can have unique properties…
Enhancement of fusion at near and sub-barrier energies for neutron-rich light nuclei
Varinderjit Singh, J. Vadas, T. K. Steinbach +8
Measurement of the fusion cross-section for neutron-rich light nuclei is crucial in ascertaining if fusion of these nuclei occurs in the outer crust of a neutron star. We have ther…
Effect of topological defects on "nuclear pasta" observables
A. S. Schneider, D. K. Berry, M. E. Caplan +2
[Background] The "pasta" phase of nuclear matter may play an important role in the structure and evolution of neutron stars. Recent works suggest nuclear pasta has a high resistivi…
