Abstract Presently seven nearby radio-quiet isolated neutron stars discovered in ROSAT data and characterized by thermal X-ray spectra are known. They exhibit very similar properties and despite intensive searches their number remained constant since 2001 which led to their name “The Magnificent Seven”. Five of the stars exhibit pulsations in their X-ray flux with periods in the range of 3.4 s to 11.4 s. XMM-Newton observations revealed broad absorption lines in the X-ray spectra which are… 
The spectral and temporal variability of the isolated X-ray pulsar RX J0720.4-3125
The radio-quiet thermally emitting X-ray pulsar RX J0720.4-3125 belongs to a group of seven isolated neutron stars (often referred to as the ``Magnificent Seven"). They share similar properties such
Spectral and temporal variations of the isolated neutron star RX J0720.4-3125: new XMM-Newton observations
Context. In the past, the isolated, radio-quiet neutron star RX J0720.4−3125 showed variations in its spectral parameters (apparent radius, temperature of the emitting area and equivalent width of
Detailed X-ray spectroscopy of the magnetar 1E 2259+586
Magnetic field geometry is expected to play a fundamental role in magnetar activity. The discovery of a phase-variable absorption feature in the X-ray spectrum of SGR 0418+5729, interpreted as
A Joint NICER and XMM-Newton View of the “Magnificent” Thermally Emitting X-Ray Isolated Neutron Star RX J1605.3+3249
Thermally emitting X-ray isolated neutron stars represent excellent targets for testing cooling surface emission and atmosphere models, which are used to infer physical parameters of the neutron
Cyclotron lines in highly magnetized neutron stars
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
Hard X-Ray Excess from the Magnificent Seven Neutron Stars
We report significant hard X-ray excesses in the energy range 2-8 keV for two nearby isolated neutron stars RX J1856.6-3754 and RX J0420.0-5022. These neutron stars have previously been observed in
Discovery of Pulsations and a Possible Spectral Feature in the X-Ray Emission from Rotating Radio Transient J1819?1458
PSR J1819-1458 is a rotating radio transient (RRAT) source with an inferred surface dipole magnetic field strength of 5 × 1013 G and a 4.26 s spin period. We present XMM-Newton observations of the
Thermal emission from magnetised neutron stars
X-ray dim isolated neutron stars and magnetars are neutron stars with strong magnetic fields, B ∼ 1013− 1015 G. Under these magnetic fields, the properties of the matter and the vacuum are expected
>“Resolving” neutron stars physics and geometry
The unprecedented harvest of X-ray photons detected from dozens of isolated neutron stars has made it possible to glimpse at their emission mechanisms as well as at their emission geometry. Rotating
CHANDRA OBSERVATIONS OF THE HIGH-MAGNETIC-FIELD RADIO PULSAR J1718–3718
High-magnetic-field pulsars represent an important class of objects for studying the relationship between magnetars and radio pulsars. Here we report on four Chandra observations of the
