Description
Observations from ground- and space-based instruments have lead to the discovery of remarkable astrophysical phenomena that are thought to be intimately related to the physics of neutron-star crusts like pulsar sudden spin-ups (so called “glitches”), quasi-periodic oscillations in the giant flares from soft gamma-ray repeaters, X-ray bursts and superbursts, or the cooling of quasi-persistent soft X-ray transients. The crust composition is also essential to evaluate the possible contribution of neutron stars to the galactic enrichment in the so-called r-process nuclei, whose origin remains one of the major mysteries in astrophysics. During this talk, we will present the latest developments of the Brussels-Montreal collaboration in the modelling of neutron-star crusts using accurately calibrated nuclear energy density functionals based on generalized Skyrme effective interactions.
