Lectures Summary:

=====================================================================================================================================

Beatriz Barbuy (USP, Brazil) & Jorge Meléndez (USP, Brazil): Spectroscopy of cool stars 

=====================================================================================================================================

We will describe atomic and molecular spectral lines observed in spectra of cool stars, and how to measure them. The analysis of stellar spectra and derivation of stellar parameters effective temperature, gravity, metallicity and microturbulence velocity will be explained. Spectrum synthesis will be described. Where to access data bases on line oscillator strengths, and other atomic physics parameters, and line lists of molecular lines will be given. Elements of nucleosynthesis will be described.

=====================================================================================================================================

Peter Beiersdorfer (Lawrence Livermore National Laboratory, USA):  Modern techniques in plasma spectroscopy in astrophysics

=====================================================================================================================================

Spectroscopy in the extreme ultraviolet (EUV) and x-ray regime provides a window on the hottest plasmas and the most energetic prcoesses in the universe. It is used, for example,  to derive metal abundances, temperatures, flow velocities, and densities. In this lecture I will describe targeted experiments using plasma sources on Earth to reproduce various aspects of the conditions thougtht to exist in the universe in order to test and improve our understanding of x-ray and EUV spectra from astrophysical objects.

Claudio Mendoza (Western Michigan University, USA): High-resolution X-ray spectroscopy on the eve of Astro-H

=====================================================================================================================================

With the launch of the Chandra and XMM-Newton space observatories in 1999, X-ray astronomy came of age,where a series of exciting discoveries have led to unprecedented breakthroughs in, for instance,cosmology, the physics of compact objects, production of heavy elements in supernova remnants, the feedback of active-galactic-nuclei in galaxies and the magneto-hydrodynamics of flares and coronal loops. The new Astro-H mission (February 2016) will provide a combination of a wide band (5-80 keV) and the improved resolution of ~5 eV in the 0.3-10 keV bandpass. It is expected to open new research endeavors related to the large-scale structures of the universe, strong gravitational fieldsand the formation and evolution of galaxies and galaxy clusters. In the present talk we give an overview of the atomic properties of the observed lines, the plasma diagnostics that are used, research highlights, the Astro-Hspectral capabilities and its new science objectives.

=====================================================================================================================================

Alla Safronova (University of Nevada-Reno, USA): X-ray spectroscopy of Z-pinches

 ====================================================================================================================================

The lecture will begins with a description of atomic processes including X-ray line polarization and then moves to non-LTE calculations and importance of EBIT data for benchmarking of atomic data. The examples of X-ray K-, L-, and M-shell spectra produced on 1 MA Z-pinch generator and their interpretation will be considered as well as some of the X-ray spectra relevant to astrophysics.

=====================================================================================================================================

Grazyna Stasinska (Observatoire Paris-Site de Meudon-LUTH, France): Problems of abundance determinations in emission-line nebulae

 ====================================================================================================================================

I will present the different methods to determine the chemical composition of emission-line nebulae (mainly HII regions and planetary nebulae), emphasizing the advantages and drawbacks of each of them. I will then discuss some of the still unsolved problems that plague the abundances derived from nebular emission lines (abundance discrepancies, temperature fluctuations, abundance inhomogeneities, kappa distribution of free electrons).
