The neutral hydrogen distribution and motion were studied in details with the RATAN- 600 in a very extended galactic region.This region is located in Scorpius-Opiuchus includ- ing the Scorpius OB-2 association, several nebulae, and the HII lamentary structures around them. The Local Bubble displ...
The equation of ( ) gives a very accurate description of the cycle of the sun and the moon, the movement of the planets and even the movement of the nebulae and other phenomena of the celestial bodies. A、Newton B、Darwin C、LuJi D、A.Pope
Analysis of emission lines in gaseous nebulae yields direct measures of physical conditions and chemical abundances and is the cornerstone of nebular astrophysics. Although the physical problem is conceptually simple, its practical complexity can be overwhelming since the amount of data to be analyzed st...
