Hybrid stars containing the 2SC+<dd> phase cool more slowly than those with the 2SC phase because inherited 3P2 superfluidity suppresses quark beta decay, producing cooling curves close to the CFL case.

Microscopic DFT+QRPA calculation shows the effective coupling constant between nuclear clusters and superfluid phonons in the neutron-star inner crust is substantially smaller than hydrodynamical estimates due to suppression of the phonon amplitude inside and around the clusters.
Gross-Pitaevskii simulations show Josephson coupling creates a bound composite of one ^1S0 SQV and two ^3P2 HQVs that can depin from pinning sites.
Hybrid star model with core quark pasta pinning superfluid vortices produces glitch amplitudes ΔΩ/Ω of order 10^{-6} matching Vela-like pulsar observations.
A review of spin effects, superfluidity, and magnetic fields in neutron matter and their influence on neutron-star structure, superfluid phases, and rotational dynamics.

Cooling of Hybrid Stars with a 2SC+$<dd>$ Phase
Hybrid stars containing the 2SC+<dd> phase cool more slowly than those with the 2SC phase because inherited 3P2 superfluidity suppresses quark beta decay, producing cooling curves close to the CFL case.

Interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust
Microscopic DFT+QRPA calculation shows the effective coupling constant between nuclear clusters and superfluid phonons in the neutron-star inner crust is substantially smaller than hydrodynamical estimates due to suppression of the phonon amplitude inside and around the clusters.
