Étoiles carbonées
Carbon stars are evolved cool giants (and some time dwarf) with
circumstellar shells or clouds of carbon dust material. The typical
temperature surface range from 2000K and 3000K. The apparent color of
this stars is deep red and all are irregular or semi-regular
variables.
The C2 Swan bands dominate the spectral
distribution (at wavelength of 4380A, 4738A, 5165A, 5635A, 6122A).
Also visible are the absorption C3 bands (4056A), CN (i.e. cyanogen
at 3880A, 4217A, 7699A), CH and SiC2 bands, and often strong Na line
at 5893A. One of the classification scheme of spectra is like C2,3.
The first number indicates decreasing temperature from 0 to 9 (2 for
the example). The second number indicates strength of the carbon
bands from 1 to 5 (3 for the example). Carbon stars are also
classified into N and R series, where N stars are older stars. An N9
star is redder and cooler than a N1 star.
The list below is adapted from Stephenson,
1989, catalogue of Cool Galactic Carbon Stars (2 Ed.) and contain
carbon stars brighter then Mv<8.5. Epoch= J2000. See: http://vizier.u-strasbg.fr/viz-bin/Cat?III/156
