... 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. ...

A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...

How the rings were formed. ... Because of the velocity of mutual collisions increases at the approaching to the planet, there is a region near an every planet where the particles reaching the definite sizes begin to pull due to the mutual collisions. ... Any big particle passes the whole cycle from the destruction to the restoration. ... Why the rings are so flat? ... The gravitation compresses the system from all sides and the rotation axis, but it cannot prevent compression along the axis. ...
