abstract
X-ray pulsars (XRPs) are accreting strongly magnetised neutron stars (NSs) in binary systems with, as a rule, massive optical companions. Very reach phenomenology and high observed flux put them into the focus of observational and theoretical studies since the first X-ray instruments were launched into space. The main attracting characteristic of NSs in this kind of system is the magnetic field strength at their surface, about or even higher than $10^{12}\,{\rm G}$, that is about six orders of magnitude stronger than what is attainable in terrestrial laboratories. Although accreting XRPs were discovered about 50 years ago, the details of the physical mechanisms responsible for their properties are still under debate. Here we review recent progress in observational and theoretical investigations of XRPs as a unique laboratory for studies of fundamental physics (plasma physics, QED and radiative processes) under extreme conditions of ultra-strong magnetic field, high temperature, and enormous mass density.

Magnetospheric flows in X-ray pulsars II: Heating, cooling and ionization degree at sub-critical accretion
Sub-critical magnetospheric accretion flows in X-ray pulsars cool to tens of eV near the surface and become partially ionized, contrary to the standard fully-ionized assumption.

Gamma-ray lines, electron-positron annihilation, and possible radio emission in X-ray pulsars
Accreting X-ray pulsars are predicted to produce detectable gamma-ray lines at 2.2-67.5 MeV plus a 511 keV annihilation line, with observability limited by magnetospheric absorption and radiative deceleration.

Studying the Variable Continuum and Emission Line Spectrum of 4U 1700-377 using NuSTAR's Stray Light
NuSTAR focused plus stray-light data of 4U 1700-377 reveal model-dependent high-energy emission lines, no conclusive CRSF, and extended low-flux states whose continuum softens without increased absorption.

Physics of Strong Magnetism with eXTP
The eXTP mission's planned instruments would enable more sensitive X-ray polarization and timing observations of magnetars and accreting pulsars, potentially testing vacuum birefringence and probing magnetic field structures.
