Based on recent Hubble Space Telescope (HST) observations in the far-UV and ground-based observations in optical bands, Pavlov and colleagues have revealed a thermal component in the spectrum of the old pulsar B0950+08 (spin-down age 17.5 Myr) and estimated a neutron star (NS) surface temperature of (1–3) × 105 K. Our new HST observations in the optical have allowed us to resolve the pulsar from a close-by galaxy and measure the optical fluxes more accurately. Using the newly measured fluxes…

Capture of electroweak multiplet dark matter in neutron stars

If dark matter has a sizable scattering cross section with nucleons, it can efficiently be captured by a neutron star. Its energy is then transferred to the neutron star as heat through the scattering

Pulsar Glitches: A Review

∼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 helping to understand

Neutron star heating in dark matter models for the muon g − 2 discrepancy

The observed value of the muon magnetic dipole moment, which deviates from the Standard Model prediction by 4.2σ, can be explained in models with weakly-interacting massive particles (WIMPs) coupled

Context. Our knowledge of the optical spectra of Isolated Neutron Stars (INSs) is limited by their intrinsic faintness. Among the fourteen optically identified INSs, medium resolution spectra have

Hubble Space Telescope Nondetection of PSR J2144–3933: The Coldest Known Neutron Star

We report nondetections of the ∼3 × 108 yr old, slow, isolated, rotation-powered pulsar PSR J2144–3933 in observations with the Hubble Space Telescope in one optical band (F475X) and two

Internal heating of old neutron stars: contrasting different mechanisms

Context. The standard cooling models of neutron stars predict temperatures of T 10 7 yr. However, the likely thermal emission detected from the millisecond pulsar J0437-4715, of spin-down age t s ~7

We use the Bayesian approach to write the posterior probability density for the three-dimensional velocity of a pulsar and for its kinematic age. As a prior, we use the bimodal velocity distribution
