Willi Schäfer,Dietmar Stahl,Enrico Mönken 25 years ago. I am recomputing the existing line lists including many more configurations and energy levels and producing many more lines. I am collecting more recent data from the literature, and I am extending the calculation to heavier elements and higher stages of ionization. I will produce moAIL 发表于 2025-3-30 14:13:23
Mitochondrial DNA and Heart Diseaseussion of the methods for determining effective temperature using stellar spectra is presented. The use of Balmer line profiles is explored and the role of spectral line depth ratios outlined. Equivalent width measurements are a powerful tool for determining effective temperature, via the excitationEncumber 发表于 2025-3-30 16:48:34
Cardiac Sodium–Calcium Exchanger Expressionof a star it is straightforward to compute also the gravity, but unfortunately this is possible only in a few cases. For most stars, the only chance we have to infer the surface gravity is based on the analysis of spectral features: lines and continuum. In this lecture we describe some of these methCRAB 发表于 2025-3-30 23:30:55
Cardiac Sodium–Calcium Exchanger Expression, along with the accuracy of values for the Sun, Vega and Procyon. Absolutely calibrated flux measurements enable the direct determination of effective temperature for stars with known angular diameters, and indirectly via the Infrared Flux Method and model flux-fitting.

Genes and Environment in Cancerng-length, microturbulence and macroturbulence is presented, along with a comparison of various calibrations. Overcoming some of the limitations of 1-D model atmospheres, 2-D and 3-D hydrodynamic simulations can yield improved fits to observed line profiles without the need for these parametrisation勋章 发表于 2025-3-31 07:55:11
Recent Results in Cancer Researchtmosphere diffusion develops significant abundance gradients (chemical stratification). The effects of stratification appear as changes in the observed spectral characteristics that are considered in the lecture.flavonoids 发表于 2025-3-31 10:15:55
M. Debatisse,A. Coquelle,F. Toledo,G. Buttinic equilibrium (LTE), and non-LTE (NLTE) are compared. It is emphasized that LTE is a poor approximation if radiative transitions dominate in stellar atmospheres. The equations of kinetic equilibrium and methods of their solution are discussed.Coordinate 发表于 2025-3-31 16:46:21

A Gene Complex Controlling Segmentation in ,adiative transfer models are often computed using the assumption of local thermodynamic equilibrium (LTE). Its validity is often questionable and needs to be supported by detailed studies, which build upon the consistent framework of NLTE. In this review, we outline the theory of NLTE.
