Star forming galaxy spectrum
Webb17 juli 2015 · The spectrum of a galaxy is the combined light from its billions of stars and all other radiating matter in the galaxy, such as gas and dust. In the top spectrum you … WebbThese massive stars don’t live very long, only a few million years (which is a very short amount of time compared to the billions of years it takes a galaxy to form). But while they’re alive, they emit a large amount of light, and much of that light is very energetic, in the ultraviolet part of the spectrum.

WebbThe spectrum resembles that of an H II region. This is an irregular galaxy that is undergoing an intense “burst” of star formation. Its optical spectrum is dominated by strong, sharp emission lines of H, He, and the light elements N, O, and S from the photoionized gas. WebbSome general observations about the characteristics of stars as indicated by their metallicities: 1) the disk portion of a galaxy has a range of metallicities, with Population I stars having values > -1, i.e., towards smaller negative numbers to positive numbers less than +1, whereas Population II stars have negative values beyond - 1; 2. globular clusters …
