nyájtípus
Nyájtípus refers to a classification system used to categorize different types of spectral lines emitted or absorbed by celestial objects. This system is primarily based on the excitation and ionization states of atoms present in the object's atmosphere. When light from a star passes through its atmosphere, certain wavelengths are absorbed at specific temperatures, creating dark lines in the spectrum. Conversely, when atoms in a hot gas are excited and then return to a lower energy state, they emit light at specific wavelengths, creating bright lines.
The Nyájtípus classification is particularly useful in stellar astronomy for determining a star's surface temperature. Different
Astronomers observe the spectral lines present in a celestial object's light and compare them to known patterns
