The 14 pages that link to Density wave theory, each with the reason it gives.

• Spiral galaxyRelated: It explains how spiral patterns can persist while stars move through the arms.

• Barred spiral galaxyRelated: It describes how spiral-arm patterns can coexist with a rotating central bar.

• Spiral armRelated: It explains how a spiral arm can remain prominent as its constituent matter passes through.

• Grand-design spiral galaxyRelated: It accounts for arms that remain coherent even as stars and gas move through them.

• Whirlpool GalaxyRelated: It describes how the Whirlpool’s arms can remain prominent as stars and gas move through them.

• Flocculent spiral galaxyCompared with: Its coherent wave patterns contrast with the localized structure typical of flocculent spirals.

• Messier 51Related: It offers a framework for interpreting the Whirlpool’s well-defined arms.

• Messier 81Related: It explains how M81 can maintain prominent arms without those arms being fixed collections of stars.

• Perseus ArmRelated: It offers one explanation for how spiral patterns can persist while stars orbit at different speeds.

• Orion ArmRelated: It offers one explanation for persistent spiral structure in the Milky Way.

• Pinwheel GalaxyRelated: It explains how spiral structure can persist while stars and gas orbit at different speeds.

• Unbarred spiral galaxyRelated: It accounts for spiral structure that can exist independently of a stellar bar.

• Magellanic spiralRelated: It explains organized spiral patterns that may be weak or incomplete in Magellanic systems.

• Stochastic self-propagating star formation modelCompared with: It explains organized galactic patterns through a different mechanism than local stochastic triggering.
