Carbon star

Japanese: 炭素星 - たんそせい（英語表記）carbon star
Carbon star
These stars have a clearly higher carbon content than normal stars. Their spectra are R-type and N-type. The majority are low-temperature red giants, but a small number of high-temperature ones have also been discovered. This indicates that the cores of red giants have the conditions to easily produce carbon, and is of interest in relation to the origin of chemical elements.

通常の星と比べると炭素組成比が明らかに大きい星。スペクトルはR型，N型。大多数は低温赤色巨星だが，高温のものも少数ではあるが発見されている。これは赤色巨星の中心核が炭素を生成しやすい条件を備えていることを示し，化学元素の起源にかかわり注目される。
