A Hall--Drift Induced Magnetic Field Instability
M. Rheinhardt, U. Geppert
In the presence of a strong magnetic field and under conditions as realized in the crust and the superfluid core of neutron stars the Hall--drift dominates the field evolution. We…
Neutron star cooling in transiently accreting low mass binaries: a new tool for probing nuclear matter
Andrea Possenti, Monica Colpi, Dany Page +1
We explore, using an exact cooling code, the thermal evolution of a neutron star undergoing episodes of intense accretion, alternated by long periods of quiescence (e.g. Soft X-Ray…
Turbulent dynamo action in the high-conductivity limit: a hidden dynamo
K. -H. Raedler, U. Geppert
The paper deals with a simple spherical mean-field dynamo model of -type in the case of high electrical conductivity. A spherically symmetric distribution of turbulent motions…
Recycling NSs to ultrashort periods: a statistical analysis of their evolution in the "magnetic moment vs period" plane
Andrea Possenti, Monica Colpi, Ulrich Geppert +2
We investigate the statistical evolution of magnetic neutron stars recycled in Low Mass Binary (LMB) systems, simulating synthetic populations. Irrespective to the details of the p…
Magneto-rotational and thermal evolution of magnetars with crustal magnetic fields
U. Geppert, D. Page, M. Colpi +1
Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are interpreted as young highly magnetized neutron stars (NSs). Their X-ray luminosity in quiescence, exceeding 1…
