Cooling of Neutron Stars: Two Types of Triplet Neutron Pairing
We consider cooling of neutron stars (NSs) with superfluid cores composed of neutrons, protons, and electrons (assuming singlet-state pairing of protons, and triplet-state pairing of neutrons). We mainly focus on (nonstandard) triplet-state pairing of neutrons with the |mJ | = 2 projection of the total angular momentum of Cooper pairs onto quantization axis. The specific feature of this pairing...
متن کامل1S0 neutron pairing vs. observations of cooling neutron stars
As shown recently by Kaminker et al. (2001), current observations of thermal emission of isolated middle-aged neutron stars (NSs) can be explained by cooling of NSs of different masses with the cores composed of neutrons, protons and electrons, assuming rather strong superfluidity (SF) of protons, weak triplet-state SF of neutrons and neglecting singlet-state SF of neutrons. We show that this e...

متن کامل0 Triplet Pairing in Neutron Matter
The separation method developed earlier by us [Nucl. Phys. A598 390 (1996)] to calculate and analyze solutions of the BCS gap equation for S0 pairing is extended and applied to P2– F2 pairing in pure neutron matter. The pairing matrix elements are written as a separable part plus a remainder that vanishes when either momentum variable is on the Fermi surface. This decomposition effects a separa...
متن کاملValence pairing , core deformation and the development of two - neutron
We explore the evolution of the structure of the ground state of a nucleus with two valence nucleons as the system approaches the two particle threshold. We use a three-body model of core+ n+ n where the core is deformed and allowed to excite. We find that both NN correlations and correlations due to deformation/excitation of the core inhibit the formation of halos. Our results suggest that it ...
