| 英文摘要 | The onset of S-1(0) proton spin-singlet pairing in neutron-star matter is studied in the framework of the BCS theory including medium polarization effects. The strong three-body coupling of the diproton pairs with the dense neutron environment and the BCS self-energy effects severely reduce the gap magnitude, so to reshape the scenario of the proton superfluid phase inside the star. At low density the vertex corrections due to the medium polarization are attractive in most isospin-asymmetry range and tend to favor that pairing. However quantitative estimates of their effect on the energy gap do not give significant changes. Implications of the new scenario on the role of the S-1(0) proton pairing in neutron-star cooling are briefly discussed. (C) 2019 Elsevier B.V. All rights reserved. |
