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. ...

... The parameter y   characterizes the ratio between the gravitational and magnetic ``properties'' of a star and will, therefore, be called the gravimagnetic parameter . Two magnetic rotators having quite different magnetic fields, subjected to different external conditions but with identical gravimagnetic parameters, have similar magnetospheres, as long as the accretion rate is quite low ( ). ... For isolated rotators, the accretion rate  yr is assumed. ...

... 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. ...
