#astrospectroscopy
- Astrospectroscopy — An elite branch of practical astrophysics dealing with the photography, digital recording, and structural analysis of the electromagnetic radiation spectra emitted or absorbed by celestial bodies. By decomposing stellar light using prisms or diffraction gratings attached to telescopes, astrospectroscopy enables the determination of chemical composition, temperature, pressure, radial velocity, and magnetic field strength of objects in the universe.
- Astrospectroscopy — A fundamental field of astrophysics dealing with the qualitative and quantitative study of the electromagnetic radiation spectra emitted or absorbed by celestial bodies. This discipline analyzes spectral lines decomposed via diffraction gratings or prisms to deduce the chemical composition, effective temperature, surface gravity, radial velocity, and rotational motions of cosmic objects in the universe.
