WebJun 9, 2024 · The Sun has an obvious emission line spectrum in the UV and X-ray range. Here is an example (from del Zanna & Mason 2024 ). The (optically) thin chromosphere and corona are not heated by radiation from below. That could not produce the temperature inversion that is seen. In physics and optics, the Fraunhofer lines are a set of spectral absorption lines named after the German physicist Joseph von Fraunhofer (1787–1826). The lines were originally observed as dark features (absorption lines) in the optical spectrum of the Sun (white light) .
