Web25.1 The Architecture of the Galaxy. The Milky Way Galaxy consists of a thin disk containing dust, gas, and young and old stars; a spherical halo containing populations of very old stars, including RR Lyrae variable stars and globular star clusters; a thick, more diffuse disk with stars that have properties intermediate between those in the thin disk and the halo; a … WebThe Evolutionary Pathways of Disk-, Bulge-, and Halo-dominated Galaxies. To break the degeneracy among galactic stellar components, we extract kinematic structures using the framework that was described in Du et al. For example, the concept of stellar halos is generalized to weakly rotating structures that are composed of loosely bound stars ... Scientists sometimes categorize galaxies based on their shapes and physical features. Other classifications organize galaxies by the activity in their central regions – powered by a supersized black hole – and the angle at which we view them. See more Our Milky Way is one example of a broad class of galaxies defined by the presence of spiral arms. These galaxies resemble giant rotating pinwheels with a pancake-like disk of stars and … See more Elliptical galaxies have shapes that range from completely round to oval. They are less common than spiral galaxies. Unlike spirals, elliptical galaxies usually contain little gas and dust … See more Irregular galaxies have unusual shapes, like toothpicks, rings, or even little groupings of stars. They range from dwarf irregular galaxies with 100 million times the Sun’s mass to large ones weighing 10 billion solar masses. … See more Lenticular galaxies are a kind of cross between spirals and ellipticals.
