碳行星 Carbon planet（重定向自Carbide planet）
   碳行星（Carbon planet），又称为钻石行星或碳化物行星，是Marc Kuchner在恒星理论中提出来假设的行星类型，它们形成于富含碳但缺乏氧的原行星盘，根据行星科学，它们的发展将不同于地球、火星和金星等这些以硅-氧化合物为主要成分的行星。这个理论已有广大的支持者，现在是由研究员Jade Bond 创建合理的想法。具体来说，不同的系统会有不同的碳和氧的比率，而我们太阳系的类地行星是倾向于氧行星。

Carbon planet 碳行星（重定向自Carbide planet）
A carbon planet is a theoretical type of planet that contains more carbon than oxygen. Marc Kuchner and Sara Seager coined the term "carbon planet" in 2005 and investigated such planets following the suggestion of Katharina Lodders that Jupiter formed from a carbon-rich core. Prior investigations of planets with high carbon-to-oxygen ratios C/O include Fegley & Cameron 1987. Carbon planets could form if protoplanetary discs are carbon-rich and oxygen-poor. They would develop differently from Earth, Mars, and Venus, which are composed mostly of silicon–oxygen compounds. The theory is now built on reasonable scientific ideas and has gained support. Different planetary systems have different carbon-to-oxygen ratios, with the Solar System's terrestrial planets are closer to being "oxygen planets". The unconfirmed exoplanet PSR J1719-1438 b, discovered on August 25, 2011, as well as the planet 55 Cancri e, could be such planets. |
