The radiation belts around the planets are the interrnal regions of planets' magnetospheres where the own magnetic field of a planet keeps the charged particles (protons and electrons) having the great kinetic energy. ... They usually distinguish the Earth's internal and external radiation belts. the internal radiation belt of the Earth has the maximum particles density (mainly protones) over the equator in the height of 22 thousand km. ... Jupiter and Saturn have the powerful radiation belts. ...

Introduction This catalogue contains mainly the atomic data needed in the astrophysical investigations of low-density plasma. It is a revised and extended version of the "Catalogue of Atomic Data for the Rarefied Astrophysical Plasma" (Golovatyj et al. ... Low-density plasma. ... In the present study we represent only the atomic data for computation of sp ectra of low-density astrophysical plasma (most known kinds of it are gaseous nebulae), their thermal and ionization structure. ...

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...

... Remote Sensing of Fire Intensity and Burn Severity in Forests of Central Siberia . ... Increasingly sophisticated and comprehensive estimates of burned areas and of active fire areas are being produced using satellite imagery. However, accurate regional estimates of fire intensity, ecosystem fire effects, and fire emissions to the atmosphere require development of accurate remote-sensing based methods for estimating the intensity of active fires and the severity of fire impacts. ...
