Atomic Data Needs for X-ray Astronomy Edited by: Manuel A. Bautista and Timothy R. Kallman NASA Goddard Space Flight Center, Greenbelt, Maryland Anil K. Pradhan The Ohio State University, Columbus, Ohio National Aeronautics and Space Administration Goddard Space Flight Center Greenbelt, Maryland October This publication contains written versions of most of the invited talks presented at the workshop on "Atomic Data Needs for X-ray Astronomy," which was held at NASA's Goddard Space Flight Center on DecemberCited by: The idea of hosting such a workshop emerged from an imminent need to update and complete current atomic datasets in anticipation of a new era of high quality X-ray spectra starting with the launching of Chandra and XMM-Newton observatories.

At first, our vision of the workshop was of a short and limited attendance event, given the specialization of the topic. The broad range of atomic data needs for X-ray astrophysics is unsurprising when considering the two-decade range of the X-ray bandpass (–10 keV) and the plethora of plasma situations to be found in astrophysics.

In the late ’s, significant attention was given to known issues, thanks to the imminent launches of XMM-Newton and by: 9. Download Citation | Atomic Data Needs for X-ray Astronomy | With the launches of the Chandra X-ray Observatory and XMM-Newton, high resolution X-ray spectra of cosmic sources are broadening.

Astrophysical X-ray spectroscopy promises huge potential scientific returns. The soft X-ray bandpass, keV, contains transitions from the K- L- and M-shell of every cosmically abundant element and ion except H and He.

With only moderate (R ~ ) resolution, these transitions can be separated into gas, molecular, and solid state phases. interpretation. The importance of atomic data to the field of x-ray astronomy comes from the fact that there are many atomic features in the x-ray band and the physical conditions in the sources are usually far from thermodynamic equilibrium, so that interpretation of line fluxes or.

Handbook of X-ray Astronomy Edited by Keith A. Arnaud, ', Randall K. Smith and Aneta Siemiginowska3 need for more systematic training of graduate students interested in X-ray astronomy became clear, leading to a series of X-ray "schools." the appendices contain a range of useful tables, including atomic Size: KB.

This publication contains written versions of most of the invited talks presented at the workshop on "Atomic Data Needs for X-ray Astronomy," which was held at NASA's Goddard Space Flight Center on December  The goal of the AtomDB project is not to generate atomic data, but to collect it from existing calculations and distribute the data to the X-ray astronomy community in useful formats.

When there is no readily available published atomic data for a particular process or transition we will calculate and include it; however, we will replace this. This is a very useful reference book for working astronomers and astrophysicists.

Forming the proceedings of a recent IAU meeting where the availability and the needs of atomic and molecular data were discussed, the papers published here discuss existing and planned instruments for astronomical spectroscopy from earth-orbiting satellites.

In particular, the atomic and molecular parameters that Cited by: This publication contains written versions of most of the invited talks presented at the workshop on Atomic Data Needs for X-ray Astronomy which was held at NASA's Goddard Space Flight Center on December 7 The idea of hosting such a workshop emerged from an imminent need to update and complete current atomic datasets in anticipation Author: Nicholas E.

The measurements are producing large sets of reliable atomic data, which include ionization and recombination cross sections for charge balance calculations, as well as line lists, excitation cross sections, and dielectronic recombination rates for interpreting X-ray line by: We report on the XSTAR atomic database that contains a large quantity of atomic rates for use in spectral modeling of astrophysical plasmas.

The database includes atomic energy levels, line wavelengths, radiative transition probabilities, electron impact excitation rates, photoionization cross section, recombination rate coefficients, electron impact ionization rates, and fluorescence and Cited by:
