Spectroscopy
- Each element has a specific emission and absorption spectrum
- These can be used to determine the composition of stellar objects
- The shifting of these lines from left to right can tell us if the object is approaching or receding from us
- The more smeared out the lines appear, the faster the star is spinning
- The occasional appearance of absorption lines very close to eachother can tell us that it is a binary star system
- Denser objects have thinner emission spectra whereas less dense objects have broader emission spectra

Have a nice week!
