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.

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.

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.

From proto-neutron star dynamo to low-field magnetars [PDF]

open access: yes
International audienceLow-field magnetars have dipolar magnetic fields that are 10-100 times weaker than the threshold, $B \gtrsim 10^{14}$ G, used to define classical magnetars, yet they produce similar X-ray bursts and outbursts. Using the first direct

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.

Characteristic electromagnetic waves caused by tensorial and possible nontensorial thermal high-frequency gravitational waves from magnetars

open access: yesNuclear Physics B, 2019
Interaction between the gravitational waves (GWs) and the strong magnetic fields would lead to the perturbed electromagnetic waves (EMWs). Magnetars can have ultra-strong surface magnetic fields ∼1011Tesla, and meanwhile, they would generate the thermal ...

The strongest magnetic fields in the universe: How strong can they become?

open access: yesFrontiers in Physics, 2014
Magnetic fields in the universe are in general weak, of the order of µGauss only. However, in compact objects they assume extraordinarily large values. These are produced by gravitational collapse of massive magnetised objects.

Supernova remnants with magnetars: Clues to magnetar formation [PDF]

open access: yesAdvances in Space Research, 2008
I discuss the lack of observational evidence that magnetars are formed as rapidly rotating neutron stars. Supernova remnants containing magnetars do not show the excess of kinetic energy expected for such a formation scenario, nor is there any evidence for a relic pulsar wind nebula.
