Atoms in the strong magnetic fields of magnetic white dwarfs and neutron stars — •Christoph Schimeczek and Günter Wunner — 1. Institut für Theoretische Physik, Universität Stuttgart, 70550 Stuttgart
The analysis of high resolution magnetic white dwarf spectra (Sloan Digital Sky Survey) and neutron star spectra (Chandra & XMM-Newton) sets the demand for precise atomic data of atoms and ions from hydrogen to iron at magnetic field strengths ranging from 102 T to 1010 T. We present values for transition energies and oscillator strengths obtained with our fast and precise tools for arbitrary magnetic field strengths and atomic states, reaching a relative precision of 10−6 for hydrogen and 10−2 for heavier elements up to iron. This provides an important contribution to the understanding of these fascinating objects.
