Using results from the early infrared satellites, Tom found that certain carbon stars invisible at ordinary wavelengths and having anomalous quantities of silicon-rich dust emitting at 9.
Spectroscopic changes and the variable mean light of carbon stars Monthly Notices of the Royal Astronomical Society, 286, 839-847.
He recognised that the reddest stars are carbon stars
, and from tabulated colour indices selected WZ Cas and its visual companion as having the greatest contrast of any pair, at least as far as magnitude 8.
Stars like IRC+10216 are known as carbon stars
and are thought not to make much water.
The stellar ejecta of these extreme carbon stars
throws carbon into the interstellar medium where it can feed the creation of carbon-rich molecular clouds.
The reddest stars in the sky are of course the carbon stars
, whose light is intrinsically reddened by chemical processes within their atmospheres, giving them highly positive B-V colour index values.
6 magnitude--one of the sky's brightest carbon stars
According to their research, the observations of SCP 06F6 bear remarkable resemblance to a group of stars containing extremely large proportions of carbon, hence dubbed carbon stars
Skrutskie of the University of Virginia in Charlottesville and Martin Weinberg of the University of Massachusetts zeroed in on carbon stars
, the brilliant, final stage of stars that weigh one to four times as much as the sun.
The stars in the Sloan survey, however, are about twice as old as the carbon stars
Stars more massive than the sun end their lives as carbon stars
, which in our galaxy are a rich source of dust.
