Title: On magnetized neutron stars

Abstract

In this work we review the formalism normally used in the literature about the effects of density-dependent magnetic fields on the properties of neutron and quark stars, expose some ambiguities that arise and propose a way to solve the related problem. Our approach explores more deeply the concept of pressure, yielding the so called chaotic magnetic field formalism for the stress tensor. We also use a different way of introducing a variable magnetic field, which depends on the energy density rather than on the baryonic density, which allows us to build a parameter free model.

  • Accretion onto magnetized neutron stars incorporated into close binary systems is considered. The shape of the boundary of the magnetosphere for two limiting cases is found within the framework of the two-flux model of nonradial accretion. It is shown that the magnetospheres of long-period x-ray pulsars (periods of more than approx.10 sec) are closed. The magnetospheres of pulsars with shorter periods may be open, and in this case they may be sources of magnetic-rotator emission (generating relativistic particles, gamma radiation and softer synchrotron radiation). For a magnetized neutron star in a binary system there is a preferred state (the ''spin-orbital''more » mode) in which the decrease in the angular momentum of the neutron star caused by magnetic-rotator emission is exactly compensated for by the moment imparted by the accreting matter. For the standard parameters the ''spin-orbital'' period of a neutron star proves to be on the order of 0.1 sec.« less
  • The problem of the deceleration of ionized hydrogen plasma is examined for the case in which the gas is infalling onto the surface of a strongly magnetized neutron star. We obtain the dynamic and thermal structure of the lower part of the accretion column by solving the time-independent hydrodynamic equations together with the radiation moment equations. Depending on the accretion rate per unit area we find that the deceleration of the infalling protons is achieved either by Coulomb friction with the ambient plasma at the lowest part of the column, or in a radiative collisional shock just above the surface.more » The possibility of collisionless, adiabatic shock is analyzed carefully. We find that such a shock front cannot exist above magnetized neutron stars, unless the accretion rate per unit are is smaller than approx.10/sup 4/ g cm/sup -2/ s/sup -1/.« less
  • Hot plasmas that produce continuum X-rays from X-ray binaries are found to produce negligible amounts of iron K photons. The reason is that because of intense X-ray fluxes inside the continuum sources, virtually all iron atoms are fully stripped. In contrast, the atmosphere of the neutron star in an X-ray binary might be an important source of iron K photons (epsilonapprox. =6.5 keV), because it is bombarded by a large number of hard X-rays capable of photo-ejecting K-shell electrons from iron atoms. If the continuum source is located in the 10/sup 5/--10/sup 6/ cm range above the neutron star surface,more » the equivalent width of the iron line blend due to the neutron star can be approx.300 eV. If the magnetic field at the surface is < or approx. =2 x 10/sup 11/ gauss, then the energy shift due to the Zeeman effect is small enough so that the observed iron line features of X-ray binaries may be accounted for by fluorescent iron K photons from the neutron star surface. If fluorescent K photons produced by the neutron star surface are dominant over iron K photons produced by surrounding materials, or if the energy shift due to the Zeeman effect and the gravitational redshift is adequate for distinguishing the former from the latter, one can get information about the magnetic field strength and the gravitational potential at the neutron star surface and the direction of the magnetic dipole axis. If the height of the continuum source is less than 10/sup 5/ cm, backscattered continuum X-rays might play an important role in determining the pulse-phase dependences of the flux and spectrum of the X-ray continuum.« less
  • The continuum spectrum of a rotating equatorial emitting region on the surface of an accreting neutron star is investigated within the Schwarzschild spacetime. It is found that the dominant general relativistic effect is the increase in apparent emission area from the neutron star surface due to gravitational light bending. For typical neutron star parameters, the apparent area of the accretion belt is remarkably independent of the viewing angle and, hence, the contribution for a boundary layer to the total X-ray luminosity is found to depend only weakly on the inclination angle of the binary system. For a blackbody spectrum inmore » the local rest frame of the emitting surface, the distortion of the spectral shape by longitudinal and transverse Doppler shifts is minimal for neutron stars rotating at periods greater than about 2 ms. It is shown that the failure to detect a blackbody component from the weakly magnetized neutron star surface in some X-ray burst sources during their quiescent state may be related to the presence of temperature variations along the vertical extent of the boundary layer. 31 refs.« less
