Stellar Life after the Main Sequence
The path a star takes after the main sequence is dependent on the star's mass. Stages 8-11 are Subgiant Branch, Red-Giant Branch, Helium Fusion/Horizontal Branch, and Asymptotic Giant Branch.
Doppler Shift
The Doppler shift is the change of a wavelength with motion, and is most used in astronomy in the field of spectroscopy
Stellar Life Interstellar Medium to the Main Sequence
The process from the interstellar medium to the main sequence is how a star forms.
HR Diagram and Star Clusters
Clusters (which come in open, associations, and globular varieties) provide the best means for us to compare theories to actual stellar evolution and can be studied via photometry and spectroscopy.
