• 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.
