Line-shape analysis is one of the most important tools for diagnostics of both laboratory and space plasmas. Its reliable implementation requires sufficiently accurate calculations, which imply the use of analytic methods and computer codes of varying complexity, and, necessarily, varying limits of applicability and accuracy. However, studies comparing different computational and analytic methods are almost non-existent. The Spectral Line Shapes in Plasma (SLSP) code comparison workshop series [1] was established to fill this gap. Numerous computational cases considered in the two workshops organized to date (in April 2012 and August 2013 in Vienna, Austria) not only serve the purpose of code comparison, but also have applications in research of magnetic fusion, astrophysical, laser-produced plasmas, and so on. Therefore, although the first workshop was briefly reviewed elsewhere [2], and will likely be followed by a review of the second one, it was unanimously decided by the participants that a volume devoted to results of the workshops was desired. It is the main purpose of this special issue.

Spectral Line Broadening by Plasmas deals with spectral line broadening by plasmas and covers topics ranging from quasi-static approximation and impact approximation to intermediate approximations and correlation effects. Experimental results for hydrogen lines, lines with forbidden components, and ionized helium lines are presented. Applications such as density and temperature measurements are also considered. Comprised of four chapters, this volume begins with an overview of the effects of electric fields from electrons and ions (both acting as point charges) on spectral line shapes. The next chapter surveys theoretical work, paying particular attention to quasi-static, impact, and intermediate approximations as well as correlation effects. Stark broadening experiments are then discussed, with special emphasis on experiments capable of checking the accuracy or validity limits of the various approximations. The final chapter is devoted to applications in laboratory plasma physics and astronomy, focusing on density and temperature measurements and opacity calculations as well as the analysis of stellar atmospheres, amplitudes and spectra of plasma waves, and radio frequency lines. This book should appeal to students, practitioners, and researchers in pure and applied physics.

Spectral lines, widths, and shapes are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects (from the solar system to the most distant objects in the universe—quasars). On the other hand, experimental and theoretical investigations of laboratory plasma have been applied in spectroscopic astrophysical research, especially in research on atomic data needed for line shape calculations. Data on spectral lines and their profiles are also important for diagnostics, analysis, and the modelling of fusion plasma, laser-produced plasma, laser design and development, and various plasmas in industry and technology, like light sources based on plasmas or the welding and piercing of metals by laser-produced plasma. The papers from this book can be divided into four groups: 1. stark broadening data for astrophysical and laboratory plasma investigations; 2. applications of spectral lines for astrophysical and laboratory plasma research; 3. spectral line phenomena in extragalactic objects, and 4. laboratory astrophysics results for spectra investigation. The reviews and research papers, representing new research on the topics presented in this book, are of interest for specialists and PhD students. We hope that the present book will be useful and interesting for scientists interested in the investigation of spectral line shapes and will contribute to the education of young researchers and PhD students.

The book presents an advanced tool for experimentalists using spectral lineshapes for diagnostics of laboratory or astrophysical plasmas, and for theorists helping the experimentalists in interpreting the experimental line profiles. It significantly expands the scope of parameters of plasmas and/or fields in it that can be measured. For some parameters, the book presents new, more advanced diagnostic methods than the methods covered in the previous books.

Studies of spectral line shapes, on the fundamental side, reveal the underlying atomic and molecular interactions. On the practical side, they are employed as powerful diagnostic tools for energy pursuit via controlled fusion, for technological gas discharges, for the atmosphere of the Earth, the Sun, and other stars.

This biennial conference is focused on the formation of spectral line profiles and with their use for diagnostic purposes. The line profiles are employed as powerful diagnostic tools for various media, such as neutral gases, technological gas discharges, magnetically confined plasmas for fusion, laser- and z-pinch-produced plasmas, astrophysical plasmas, planetary atmospheres.

Astrophysics is a branch of space science, wherein the laws of physics and chemistry are applied in order to understand the universe and its components. Spectral line shape refers to the shape of a feature observed in spectroscopy that represents an energy change in an ion, atom or molecule. The shapes and widths of spectral lines are effective instruments for absorbing and emitting gas diagnostics in various astrophysical objects. The absorption and emission lines of astrophysical objects are formed in a variety of kinematical and physical circumstances and at a distance from the observer. Data on spectral lines and their profiles is crucial for modeling, diagnostics and analysis of laser development and design, fusion plasma, and plasma produced through laser. It is also important for various plasmas in technologies such as the piercing and welding of metals by laser-produced plasma and plasma based light sources. This book provides comprehensive insights into the theory of spectral line shapes in astrophysics. Also included herein is a detailed explanation of the various roles and applications of spectral line shapes in astrophysics. This book is a vital tool for all researching and studying this area of astrophysics.
