Swan band

Index Swan band

Swan bands are a characteristic of the spectra of carbon stars, comets and of burning hydrocarbon fuels. [1]

Carbon star

A carbon star is typically an asymptotic giant branch star, a luminous red giant, whose atmosphere contains more carbon than oxygen; the two elements combine in the upper layers of the star, forming carbon monoxide, which consumes all the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a "sooty" atmosphere and a strikingly ruby red appearance.

Comet

A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing.

Diatomic carbon

Diatomic carbon (systematically named ethenediylidene and dicarbon(C—C)), also called dicarbon, is an inorganic chemical with the chemical formula C.

Emission spectrum

The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.

William Swan (physicist)

Prof William Swan FRSE PRSSA LLD (13 March 1818 in Edinburgh – 1 March 1894 in Shandon, Argyll) was a Scottish mathematician and physicist best known for his 1856 discovery of the Swan band.
