Cyclotron lines, also called cyclotron resonant scattering features are spectral features, generally appearing in absorption, in the X-ray spectra of objects containing highly magnetized neutron stars, allowing the direct measurement of the magnetic field strength in these objects. Cyclotron features are thought to be due to resonant scattering of photons by electrons in the strong magnetic fields. The main content of this contribution focusses on electron cyclotron lines as found in accreting… 

Relation of Cyclotron Resonant Energy and Luminosity in a Strongly Magnetized Neutron Star GRO J1008-57 Observed by Insight-HXMT

Cyclotron line scattering features are detected in a few tens of X-ray pulsars (XRPs) and used as direct indicators of a strong magnetic field at the surface of accreting neutron stars (NSs). In a

The accreting compact objects in most of ultraluminous X-ray sources (ULXs) are likely to be neutron stars rather than black holes as suggested by the recent detection of periodic pulsations from

Statistical features of multiple Compton scattering in a strong magnetic field

Compton scattering is a key process shaping spectra formation and accretion flow dynamics in accreting strongly magnetized neutron stars (NSs). A strong magnetic field affects the scattering cross

This paper introduces the physics surrounding accretion onto a magnetised neutron star in a binary system. It focuses on the use of experimentally observed cyclotron spectral features to estimate the

Observational diversity of magnetized neutron stars

An introductory review for non-astrophysicists about the observational properties of highly-magnetized NSs, and how the five fundamental quantities of NSs change with evolution of, and vary depending on the class of, the NSs is presented.

Meta-analysis of electron cyclotron resonance absorption features detected in high-mass X-ray binaries

Using recent compilations of detailed X-ray observations and spectral models of exceptional quality, we record the electron cyclotron resonance absorption (ECRA) features that have been detected in

Ultra-compact X-ray binaries as dual-line gravitational-wave sources

By virtue of their sub-hour orbital periods, ultra-compact X-ray binaries are promising sources for the space-borne gravitational-wave interferometers LISA, Taiji, and TianQin. Some of these systems

Early neutron star evolution in high-mass X-ray binaries

The application of standard accretion theory to observations of X-ray binaries provides valuable insights into neutron star properties, such as their spin period and magnetic field. However, most

A Peculiar Cyclotron Line near 16 keV Detected in the 2015 Outburst of 4U 0115+63?

In 2015 October, the Be/X-ray binary 4U 0115+63 underwent a type II outburst, reaching an X-ray luminosity of ∼1038 erg s−1. During the outburst, Nuclear Spectroscopic Telescope Array (NuSTAR)

Electron-positron pairs in hot plasma of accretion column in bright X-ray pulsars

The luminosity of X-ray pulsars powered by accretion onto magnetized neutron stars covers a wide range over a few orders of magnitude. The brightest X-ray pulsars recently discovered as pulsating



Proton Cyclotron Features in Thermal Spectra of Ultramagnetized Neutron Stars

A great deal of interest has been recently raised in connection with the possibility that soft γ-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) contain magnetars, young neutron stars endowed

Magnetic Fields of Accreting X-ray pulsars

The status of the knowledge about magnetic fields of neutron stars in accreting X-ray binaries through the measurement of cyclotron lines (Cyclotron Resonance Scattering Features -- CRSF) is

New observations of the cyclotron absorption feature in Hercules X–1

ALTHOUGH neutron stars are generally believed to be born with intense (1011–1013 G) magnetic fields1,2, which then gradually decay3, measurements of their field strengths remain uncertain. In the


This paper demonstrates that a shallower and broader fundamental (= first harmonic) line and a deeper second harmonic line as observed in accreting X-ray pulsars such as Vela X–1 and A0535+26 can be produced via a superposition of a large number of cyclotron lines formed at numerous different heights in a line-forming region with a dipole magnetic field.


It is well known from pulsar physics that neutron stars must possess surface magnetic fields of the order of loio to lo” gauss or possibly even higher. These figures are derived from considerations


Cyclotron resonance scattering features observed in the spectra of some X-ray pulsars show significant changes of the line energy with the pulsar luminosity. At high luminosities, these variations

Magnetic Fields of Neutron Stars in X-Ray Binaries

A substantial fraction of the known neutron stars resides in X-ray binaries—systems in which one compact object accretes matter from a companion star. Neutron stars in X-ray binaries have magnetic
