Spectrum helps in studying binary star systems and galaxy structure by analyzing the elements, motion, rotation, and mass of stars and galaxies through spectral lines and Doppler shifts.
Spectrum helps with studying binary star systems and galaxy structure by providing information about the elements in stars and galaxies through their spectral lines. The Doppler shifts observed in the spectral lines can indicate the motion, rotation, and mass of stars and galaxies. Line broadening in the spectral lines can also provide insights into the range of speeds at which stars are moving within a galaxy, which can help calculate the mass of an elliptical galaxy.
