In this paper, a library of 183 588 synthetic spectra based on Kurucz's ATLAS9 models is presented for the far red spectral interval (7653-8747 A), characterized by 3500 K < T eff < 47500 K, 0.0 < log g ≤ 5.0, -3.5, 0 < V rot < 500 km s -1, ξ = 2 km s −1.Abstract:
A library of 183 588 synthetic spectra based on Kurucz's ATLAS9 models is presented for the far red spectral interval (7653-8747 A). It is characterized by 3500 K < T eff < 47500 K, 0.0 < log g ≤ 5.0, -3.0 < [M/H] ≤ +0.5, 0 < V rot < 500 km s -1 , ξ = 2 km s -1 . The whole grid of spectra is calculated for resolving powers 8500, 11 500 and 20 000. A section of the grid is also computed for [α/Fe] = +0.4 and for microturbulent velocities 0 and 4 km s -1 . The library covers the wavelength ranges and resolutions of the two ambitious spectroscopic surveys by the ground experiment RAVE and the space mission GAIA. Cross-sections across the multi-dimensional data-cube are used to illustrate the behaviour of the strongest spectral lines. Interpretation of real data will have to include interpolation to grid substeps. We present a simple estimate of the accuracy of such a procedure.read more

TL;DR: In this article, the current status of our knowledge of the chemical composition of the Sun is reviewed, essentially derived from the analysis of the solar photospheric spectrum, and a comparison of solar and meteoritic abundances confirms that there is a very good agreement between the two sets of abundances.

The determination of an accurate isotope dependent potential energy surface for water from extensive ab initio calculations and experimental data
TL;DR: In this article, a high quality ab initio potential energy surface (PES) and dipole moment function (DPM) for water has been determined and an adjusted PES is empirically adjusted to improve the agreement between the computed line positions and those from the HITRAN 92 data base with J⩽5 for H216O.
