INTEGRAL Observations of Magnetars

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT The INTEGRAL satellite has collected a large amount of data on magnetars in our Galaxy, spanning more than 20 years starting from 2003. The large data set obtained with the IBIS/ISGRI instrument at energies above 20 keV allows us to study both the properties and long‐term evolution of their persistent hard X‐ray emission and the population ...

Magnetars [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2017
Magnetars are young and highly magnetized neutron stars that display a wide array of X-ray activity including short bursts, large outbursts, giant flares, and quasi-periodic oscillations, often coupled with interesting timing behavior including enhanced spin-down, glitches, and antiglitches.

MAGNETAR HEATING [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We examine four candidate mechanisms that could explain the high surface temperatures of magnetars. (1) Heat flux from the liquid core heated by ambipolar diffusion. It could sustain the observed surface luminosity erg s−1 if core heating offsets neutrino cooling ...

An anti-glitch in a magnetar [PDF]

open access: yesNature, 2013
Magnetars are neutron stars showing dramatic X-ray and soft $γ$-ray outbursting behaviour that is thought to be powered by intense internal magnetic fields. Like conventional young neutron stars in the form of radio pulsars, magnetars exhibit "glitches" during which angular momentum is believed to be transferred between the solid outer crust and the ...

A search for runaway stars in 12 Galactic supernova remnants

open access: yesAstronomische Nachrichten, Volume 342, Issue 3, Page 553-577, March 2021., 2021
Runaway stars can result from core‐collapse supernovae in multiple stellar systems. If the supernova disrupts the system, the companion is ejected with its former orbital velocity. A clear identification of a runaway star can yield the time and place of the explosion, as well as orbital parameters of the pre‐supernova binary system.

Magnetars [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Recent x-ray observations have shown that a substantial fraction of newly born neutron stars have magnetic fields of several 10 14 G. They reveal themselves as soft gamma repeaters and anomalous x-ray pulsars and may account for the missing radio pulsars in young supernova remnants.

Magnetars [PDF]

open access: yesAmerican Journal of Physics, 2000
Abstract I summarize recent observational and theoretical advances in the understanding of the Soft Gamma Repeaters and the Anomalous X-ray Pulsars. Several direct physical arguments point to very strong magnetic fields (B > 10 BQED = 4.4 × 1014 G) in SGR outbursts. The connection between these two classes of neutron stars is examined.

Properties and Composition of Magnetized Nuclei

open access: yesParticles, 2020
The properties and mass distribution of the ultramagnetized atomic nuclei which arise in heavy-ion collisions and magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed.
