Solar Flare Origin - critical analysis" Lev Pusti'lnik We analyze current approach to solar flare origin in 3 aspects: a. Pre-flare equilibrium state of current-magnetic structure above active region and its evolution to flare state, b. Possible reasons of stability loss with transition of system in flare state c. Flare energy release in turbulent current sheet and particle acceleration in this system. ...

The parameters of the model resulted from a numerical fitting of various data, such as the observed distribution of the young star population and neutral hydrogen, the density of population II stars in the vicinity of the Sun, the galactic rotation curve and the dynamics and distribution of globular clusters   and dwarf irregular satellites of the Galaxy. ...

. I will present some new results pertaining to our current understanding of the structure and substructure of the stellar components of the Milky Way, including possible relations between them and insight gained into Galaxy evolution.

. Saturn's D ring, the innermost of the planet's rings, sports an intriguing structure that appears to be a wavy, or "vertically corrugated," spiral. This continuously changing ring structure provides circumstantial evidence for a possible recent collision event in the rings. NASA / JPL / Space Science Institute

... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... Meta Index / Home Page / DSS utilities . The DSS structure type RangeT is described in dsslib . It specifies a lower and an upper bound to an interval on the real line, and the types of these bounds. Possible types are INCLUSIVE (which means the bound is included in the interval), EXCLUSIVE (which means the bound is not included in the interval) and UNDEFINED in which case there is no bound at this end of the interval. ...
