Spiral Density Waves in a Gas Disk of Rigid-body Rotation
碩士 === 國立中央大學 === 天文研究所 === 89 === The observed rotation laws near the center $(<1 kpc)$ for almost all nearby spiral galaxies can be approximated by a rigid-body rotation. The density-wave theory of galactic spirals is tailored to handling a differenti...
