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 ... WebOne of the most interesting observation areas in this context is the center of the Milky Way, where the black hole with the largest angular diameter as seen from Earth is located. The compact radio source Sagittarius A* (SgrA*) at the very center of the Milky Way has been observed over more than five decades (see Genzel et al. [ 1 ] and ...

WebThe thin disk of the Milky Way has sustained ongoing star formation for 10^10 years. Consequently it contains stars with a wide range of ages, and may be divided into groups of different ages. ... Star-counts suggest that this component is distributed in a disk with a scale height of 1 to 1.5 kpc. WebMay 15, 2024 · These discs are limited in size, so that beyond certain radius there are very few stars left. ... More information: M. López-Corredoira et al.
