ATOMIC IONIZATION AND OPACITIES IN PULSAR ATMOSPHERES Hydrogen Atmospheres
نویسنده
چکیده
In the strong magnetic elds of typical radio pulsars atomic lines and photoionization edges lie in the soft X-ray part of the spectrum giving the dominant contribution to the opacity. Improved photoionization cross sections are presented for a hydrogen atmosphere and magnetic elds of 10 11 ? 10 13 G, exhibiting novel Beutler{Fano resonance features due to the contribution of autoionizing atomic levels. The eeect of atomic motion transverse to the magnetic eld is discussed in detail.

Magnetized Iron Atmospheres for Neutron Stars Mohan
Using a Hartree-Fock formalism, we estimate energy levels and photon cross sections for atomic iron in magnetic Ðelds BD 1013 G. Computing ionization equilibrium and normal mode opacities with these data, we construct LTE neutron star model atmospheres at 5.5 \ log and compute emergent (Teff) \ 6.5 spectra. We examine the dependence of the emergent spectra on and B. We also show the spectral Te...
متن کاملOpacities and spectra of hydrogen atmospheres of moderately magnetized neutron stars⋆
Context. There is observational evidence that central compact objects (CCOs) in supernova remnants have moderately strong magnetic fields B ∼ 1011 G. Meanwhile, available models of partially ionized hydrogen atmospheres of neutron stars with strong magnetic fields are restricted to B 1012 G. Extension of the applicability range of the photosphere models to lower field strengths is complicated b...
متن کاملEquation of State and Opacities for Hydrogen Atmospheres of Neutron Stars with Strong Magnetic Fields
We present an equation of state and radiative opacities for a strongly magnetized hydrogen plasma at magnetic fields B, temperatures T, and densities typical for atmospheres of isolated neutron stars. The firstand second-order thermodynamic functions, monochromatic radiative opacities, and Rosseland mean opacities are calculated and tabulated, taking account of partial ionization, for 8 1011 G ...
متن کاملPartially ionized atmospheres of neutron stars with strong magnetic fields
We construct hydrogen atmosphere models for strongly magnetized neutron stars in thermodynamic equilibrium, taking into account partial ionization. The presence of bound states affects the equation of state, absorption coefficients, and polarizability tensor of a strongly magnetized plasma. Therefore the partial ionization influences the polarization vectors and opacities of normal electromagne...
متن کاملTheoretical X-ray spectra of hot H-rich white dwarfs. Impact of new partition functions of iron, Fe V through Fe VII
In this paper we discuss new method for the atomic partition function (APF) computations, which is then applied to highly ionized iron, Fe V through Fe VII. Subsequently we have computed LTE model atmospheres of two hydrogen-rich white dwarf stars of the effective temperatures Teff = 8 × 104 K and 1.2 × 105 K, and log g = 8.0 (cgs units), which included trace abundance of iron. Both models corr...
