The Evolution of Magnetic Field and Spin Period of Accreting Neutron Stars
نویسنده
چکیده
Based on the accretion induced magnetic field decay model, in which frozen field and incompressible fluid are assumed, we obtain the following results. (1) The analytic relation between the magnetic field and spin period is obtained if the fastness parameter of accretion disk is neglected. Our model evolutionary tracks of accreting neutron stars in P-B diagram are different from the equilibrium period lines even the influence of the fastness parameter is taken into account. (2) The theoretical minimum spin period of accreting neutron stars is Max (

Period Distribution of Old Accreting Isolated Neutron Stars
In this paper we present calculations of period distribution for old accreting isolated neutron stars (INSs). After few billion years of evolution low velocity INSs come to the stage of accretion. At this stage INS's period evolution is governed by magnetic braking and angular momentum accreted. Since the interstellar medium is turbulized accreted momentum can either accelerate or decelerate sp...

متن کاملStochastic Spin Evolution of Neutron Stars
In this paper we present calculations of period distribution for old accreting isolated neutron stars (INSs). At the age about few billions years low velocity INSs come to the stage of accretion. At that stage their period evolution is governed by magnetic braking and accreted angular momentum. Due to turbulence of the interstellar medium (ISM) accreted momentum can both accelerate and decelera...
متن کاملDifferent Magnetic Field Distributions in Deformed Neutron Stars
In this work, we review the formalism which would allow us to model magnetically deformed neutron stars. We study the effect of different magnetic field configurations on the equation of state (EoS) and the structure of such stars. For this aim, the EoS of magnetars is acquired by using the lowest order constraint variational (LOCV) method and employing the AV18 potential....
متن کاملConstraining parameters of magnetic field decay for accreting isolated neutron stars
The influence of exponential magnetic field decay (MFD) on the spin evolution of isolated neutron stars is studied. The ROSAT observations of several X-ray sources, which can be accreting old isolated neutron stars, are used to constrain the exponential and power-law decay parameters. We show that for the exponential decay the ranges of minimum value of magnetic moment, μb, and the characterist...
