The Early Evolution of Magnetar Rotation I: Slowly Rotating"Normal"Magnetars [PDF]
, 2022 In the seconds following their formation in core-collapse supernovae,"proto"-magnetars drive neutrino-heated magneto-centrifugal winds. Using a suite of two-dimensional axisymmetric MHD simulations, we show that relatively slowly rotating magnetars with ...

Testing the fossil field hypothesis: could strongly magnetized OB stars produce all known magnetars? [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Stars of spectral types O and B produce neutron stars (NSs) after supernova explosions. Most of NSs are strongly magnetized including normal radio pulsars with B ∝ 1012 G and magnetars with B ∝ 1014 G.

Magnetars as laboratories for strong field QED [PDF]
AIP Conference Proceedings, 2021 A strong electromagnetic field polarizes the vacuum and in the presence of an electric field creates pairs of a charged particle and its anti-particle.

Precessing magnetars as central engines in short gamma-ray bursts [PDF]
, 2021 Short gamma-ray bursts that are followed by long-duration X-ray plateaus may be powered by the birth, and hydrodynamic evolution, of magnetars from compact binary coalescence events.

Modelling spin evolution of magnetars [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The origin and fate of magnetars (young, extremely magnetized neutron stars, NSs) remains unsolved. Probing their evolution is therefore crucial for investigating possible links to other species of isolated NSs, such as the X-ray dim NSs (XDINSs) and ...

Periodicity in recurrent fast radio bursts and the origin of ultralong period magnetars [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The recurrent fast radio burst FRB 180916 was recently shown to exhibit a 16-d period (with possible aliasing) in its bursting activity. Given magnetars as widely considered FRB sources, this period has been attributed to precession of the magnetar ...

Emission Properties of Periodic Fast Radio Bursts from the Motion of Magnetars: Testing Dynamical Models [PDF]
Astrophysical Journal Letters, 2021 Recent observations of the periodic fast radio burst source 180916.J0158+65 (FRB 180916) find small linear polarization position angle swings during and between bursts, with a burst activity window that becomes both narrower and earlier at higher ...

Stellar Core-Merger-Induced Collapse: New Formation Pathways for Black Holes, Thorne-$\dot{\rm Z}$ytkow objects, Magnetars and Superluminous Supernovae [PDF]
, 2021 Most neutron stars (NSs) and black holes (BHs) are believed to be the final remnants in the evolution of massive stars. In this study, we propose a new formation channel for the formation of BHs and peculiar NSs (specifically, magnetars and Thorne-$\dot{\

The Life Cycle of Magnetars: A Novel Approach to Estimate Their Ages [PDF]
Astrophysical Journal Letters, 2021 Anomalous X-ray pulsars and soft gamma repeaters are slowly rotating, young, and isolated neutron stars exhibiting sporadic outbursts and high X-ray quiescent luminosities.

Comparison of the characteristics of magnetars born in death of massive stars and merger of compact objects with swift gamma-ray burst data [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Assuming that the shallow-decaying phase in the early X-ray light curves of gamma-ray bursts (GRBs) is attributed to the dipole radiations (DRs) of a newborn magnetar, we present a comparative analysis for the magnetars born in death of massive stars ...
