A spectroscopic study of RV Tauri stars in the Large Magellanic Cloud showed that they have the same range of spectra as their galactic counterparts but that at least one is a carbon star with s-process elements as might be expected if they are post-AGB objects.
It was Eaglesclife car part manufacturer, Nifco UK, that proved to be the Low Carbon star at the 2012 awards.
London, Sep 15 (ANI): Using the European Herschel space telescope, astronomers have found a hot water vapour formed deep into the atmosphere of a red giant pulsating carbon star, CW Leonis.
Among the topics are the physical properties of red supergiants, the dying carbon star U Antliae, interferometric observations of supergiants, the circumstellar-interstellar boundary around evolved stars, chromospheres and the winds of cool supergiants, polarization from the structured envelopes of cool evolved stars, and a cool star mass loss rate study.
It is a carbon star which glows with a lovely reddish colour that varies irregularly between magnitude 7 and 11.
Consequently, it follows that double star systems in which one component happens to be a deeply red-tinted carbon star and the other a star of non-carbon classification, will have higher than average colour contrasts.
By comparing the luminosity of a carbon star to how bright it appears in the sky, Skrutskie, Weinberg, and their colleagues determined the distance to each of the 30,000 carbon stars in 2MASS.
Sloan and his colleagues observed dust forming around the carbon star MAG 29, located 280,000 light years away in a smaller nearby galaxy called the Sculptor Dwarf.
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.
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.
Stars like IRC+10216 are known as carbon stars and are thought not to make much water.
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.
