There are no green stars because the ‘black-body spectrum’ of stars, which describes the amount of light at each wavelength and depends on temperature, doesn’t produce the same spectrum of colours as, for example, a rainbow.
It means that visually, a star will only be green when it's burning at ONLY a green frequency (pretty slim range), or a suitable mix only in the visible spectrum (you can't have say, a mix of energy in the middle of the visible range, then skip blue and purple and go right on to UV and gamma) - which is impossible for a star to functionally do.
4 mar 2024 · So why can’t stars with temperatures in between appear green? The answer is a result of the way our eyes see combinations of frequencies: Our eyes add up all the colors that come in, and the...
31 sie 2020 · There are red stars, and orange stars, and yellow stars, and blue stars, and they are all understandable save the fact that there is a 'gap': There are no green stars. Is this because of hydrogen's chemical properties (e.g. the emission spectrum) or some other reason?

29 mar 2013 · A green star is radiating right in the center of the visible light spectrum, which means it is emitting some light in all the possible colors. The star would therefore appear...
