WebMay 5, 2013 · In section A of the procedure, you will use RR Lyrae variable stars in globular clusters to measure (1) our distance from the center of the Milky Way, and (2) the approximate size of the Milky Way. WebThe center of our disk galaxy, the Milky Way, is dominated by a boxy/peanut-shaped bulge. Numerous studies of the bulge based on stellar photometry have concluded that the bulge stars are exclusively old. The perceived lack of young stars in the bulge strongly constrains its likely formation scenarios, providing evidence that the bulge is a ...
