Magnetar field dynamics driven by chiral anomalies without magnetic helicity
Clara Dehman
The paper studies how the chiral magnetic effect can generate strong dipolar magnetic fields in magnetars even when the initial magnetic field has no net helicity, showing that loc…
Magnetic, thermal and rotational evolution of isolated neutron stars
José A. Pons, Clara Dehman, Daniele Viganò
The strong magnetic fields of neutron stars are closely linked to their observed thermal, spectral, and timing properties, such as the distribution of spin periods and their deriva…
Late-blooming magnetars: awakening as long period transients after a dormant cooling epoch
Arthur G. Suvorov, Clara Dehman, José A. Pons
Long-period transients are an elusive class of compact objects uncovered by radio surveys. While magnetars are a leading candidate for those sources that appear isolated, several o…
Revealing the nature of long-period transients with space-based gravitational-wave interferometers
Arthur G. Suvorov, Clara Dehman, José A. Pons
A few members of the recently discovered class of long-period transients have been identified as binaries with white-dwarf primaries. In most cases, however, electromagnetic data a…
Magnetar field dynamics shaped by chiral anomalies and helicity
Clara Dehman, José A. Pons
The chiral magnetic effect (CME) -- a macroscopic manifestation of the quantum chiral anomaly -- induces currents along magnetic field lines, facilitating mutual conversion between…
Reality of inverse cascading in neutron star crusts
Clara Dehman, Axel Brandenburg
The braking torque that dictates the timing properties of magnetars is closely tied to the large-scale dipolar magnetic field on their surface. The formation of this field has been…
