The triaxial system behaves like the bar mode of a disk: giving it angular momentum makes it rounder, while removing angular momentum makes it more triaxial. The relative position of the Sun can be determined by matching the COBE 3.5 μm light distribution along .=0°, and the velocity dis

The most likely scenario for the formation of these massive stars is a burst of star formation a few million years ago. Radial velocity measurements for about 300 early and late type stars b

Introduction to discourse theoryal’. Two cases are considered: (i) the putative black hole lies at the center of the dense stellar cluster and (ii) it is off the center. In the first case, the mechanism of the spiral arm generation can be over-reflection instability, and in the second case the axial asymmetry of the gravitational

Acquired Valve Disease and Processes1.2 to 1.5 in real galaxies. We consider a number of possible explanations for this discrepancy between theoretical prediction and observation, and conclude that no conventional alternative seems able to account for it.
