Doppler shift is produced by radial velocity
Delta lambda = wavelength observed- wavelength emitted by star
Each region of electro magnetic spectrum requires its own telescope
Chapter 9 Notes
Low mass stars fade in billions of years
Medium mass star .8 to 8 solar masses form a planetary nebula and leave a white dwarf
High mass stars more than 8 solar masses: Supernovae and leave a neutron star and supernova
