Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray
repeaters, have been recognized in the last decade as the most promising candidates for …

The early 21st century is witnessing a breakthrough in the study of the thermal radiation of
neutron stars. Observations with modern space telescopes have provided a wealth of …

There has recently been growing evidence for the existence of neutron stars possessing
magnetic fields with strengths that exceed the quantum critical field strength of 4.4× 10 13 G …

PSR J0740+ 6620 is the neutron star with the highest precisely determined mass, inferred
from radio observations to be 2.08±0.07 M⊙. Measurements of its radius therefore hold …

Magnetars are the most strongly magnetized neutron stars, and one of the most promising
targets for X-ray polarimetric measurements. We present here the first Imaging X-ray …

This article is a review of Soft Gamma Repeaters and Anomalous X-ray Pulsars. It contains a
brief historical record of the emergence of these classes of neutron stars, a thorough …

Topical problems in the physics of and basic facts about neutron stars are reviewed. The
observational manifestations of neutron stars, their core and envelope structure, magnetic …

Neutron stars are fascinating astrophysical objects immersed in strong gravitational and
electromagnetic fields, at the edge of our current theories. These stars manifest themselves …

The recent observations of the anomalous X-ray pulsars 4U 0142+ 61 and 1RXS J170849. 0-
400910 by the Imaging X-ray Polarimetry Explorer (IXPE) opened up a new avenue to study …

Neutron stars are associated with diverse physical phenomena that take place in conditions
characterized by ultrahigh densities as well as intense gravitational, magnetic and radiation …
