Magnetars are young and highly magnetized neutron stars that display a wide array of X-ray
activity including short bursts, large outbursts, giant flares, and quasi-periodic oscillations …

The interpretation of pulsar rotational glitches, the sudden increase in spin frequency of
neutron stars, is a half-century-old challenge. The common view is that glitches are driven by …

Radio pulsars provide us with some of the most stable clocks in the universe. Nevertheless
several pulsars exhibit sudden spin-up events, known as glitches. More than forty years after …

Matter at high density and low temperature is expected to be a color superconductor, which
is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the Fermi …

The physics of neutron star crusts is vast, involving many different research fields, from
nuclear and condensed matter physics to general relativity. This review summarizes the …

Inhomogeneous superconductivity arises when the species participating in the pairing
phenomenon have different Fermi surfaces with a large enough separation. In these …

In any context in which color superconductivity arises in nature, it is likely to involve pairing
between species of quarks with differing chemical potentials. For suitable values of the …

Spinning superfluid neutrons in the core of a neutron star interact strongly with coexisting
superconducting protons. One consequence is that the outward (inward) motion of core …

∼ 6% of all known pulsars have been observed to exhibit sudden spin-up events, known as
glitches. For more than fifty years, these phenomena have played an important role in …

We test statistically the hypothesis that radio pulsar glitches result from an avalanche
process, in which angular momentum is transferred erratically from the flywheel-like …
