In an sbb galaxy the spiral arms emanate from
WebThese galaxies are conspicuous for their spiral-shaped arms, which emanate from or near the nucleus and gradually wind outward to the edge. There are usually two opposing arms … Edwin Hubble classified spiral galaxies of this type as "SB" (spiral, barred) in his Hubble sequence and arranged them into sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at the other extreme and have loosely bound arms.

WebcD galaxies are a special case, with very extended outer envelopes not apparent in short exposures. Here the `c' prefix indicates a supergiant galaxy. The DDO System. The DDO system, developed by van den Bergh (1960a,b), combines elements of the Hubble and Yerkes systems, and introduces `quality and length of spiral arms' as a proxy for luminosity. WebMost spiral galaxies have a central bulge surrounded by a flat, rotating star disk. The bulge in the middle is composed of old, dark stars and is thought to contain supermassive black holes.
