Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...
The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons in atoms.
The study found that the early spectra of SN 2024jlf showcase flash ionization features in hydrogen-alpha, carbon and helium emission lines, which persist for about 1.3–1.8 days. The photometric ...
