Magnetars: Structure and evolution from p-star models

open access: yes, 2005
P-stars are compact stars made of up and down quarks in $\beta$-equilibrium with electrons in a chromomagnetic condensate. We discuss p-stars endowed with super strong dipolar magnetic field which, following consolidated tradition in literature, are ...

Are Gamma Ray Bursts due to Rotation Powered High Velocity Pulsars in the Halo ? [PDF]

open access: yes, 1995
The BATSE experiment has now observed more than 1100 gamma-ray bursts. The observed angular distribution is isotropic, while the brightness distribution of bursts shows a reduced number of faint events.

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

On the nature of some SGRs and AXPs as rotation-powered neutron stars

open access: yes, 2016
We investigate the possibility that some SGRs/AXPs could be canonical rotation-powered pulsars using realistic NS structure parameters instead of fiducial values.

γ-Ray Pulsar Emission is Mostly Stable on Timescales from Minutes to Years

open access: yesThe Astrophysical Journal
We present a method for the detection and characterization of random changes in the flux from γ -ray pulsars on sub-hour timescales, much shorter than variations that can be accessed using direct flux measurements.

POSTN‐Mediated Interplay of M1 Polarized Macrophage with Tendon‐Derived Stem Cells to Drive Traumatic Heterotopic Ossification Formation through PTK7/ATK Signaling?

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
The mechanism diagram reveals that the formation of trauma‐induced heterotopic ossification (HO) is accompanied by the polarization of macrophages toward the M1 phenotype. Additionally, the extracellular vesicles secreted by M1 macrophages, which contain periostin (POSTN), directly bind to PTK7 in tendon‐derived stem cells (TDSCs).

The radio and X-ray mode-switching pulsar PSR B0943+10 [PDF]

open access: yes, 2017
Observations obtained in the last years challenged the widespread notion that rotation-powered neutron stars are steady X-ray emitters. Besides a few allegedly rotation-powered neutron stars that showed "magnetar-like" variability, a particularly ...

MAGNETAR-LIKE X-RAY BURSTS FROM A ROTATION-POWERED PULSAR, PSR J1119–6127 [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT Two energetic hard X-ray bursts from the rotation-powered pulsar PSR J1119−6127 recently triggered the Fermi and Swift space observatories. We have performed in-depth spectral and temporal analyses of these two events. Our extensive searches in both observatories’ data for lower luminosity bursts uncovered 10 additional events ...

Fluorine‐Free Biomass‐Derived Ionic Liquid Electrolytes: Ion Dynamics and Electrochemical Properties

open access: yesChemistry – A European Journal, Volume 31, Issue 53, September 19, 2025.
This study presents the synthesis, physical characterization, and transport as well as electrochemical properties of a novel class of ten ionic liquids (ILs). The ILs are created with two biomass derived anions such as furan‐2‐carboxylate [FuA] and tetrahydrofuran‐2‐carboxylate [HFuA] coupled to a range of nitrogen heterocyclic cations, for which the ...
