Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...

However astronomers are refining their models of exactly how stars work all the time.Тљ The estimated age of 16 billion years had an uncertainty of two billion years from the inaccuracy of its measured distance alone, if any of the predicted details of the star?s interior processes were off this uncertainty could be larger still. ...

As of 1.3, the Apache source directories have been re-organised. This re-organisation is designed to simplify the directory structure, make it easier to add additional modules, and to give module authors a way of specifying compile time options or distribute binary modules. ... The non-module source files have moved from src into src/main . ... Configure . ... For example, say it is called mod_demo.c. The archive for this module should consist of two files, in a suitable directory name. ...
