Researchers find carbon-rich planets far more common than previously thought

Diamonds are an exoplanet hunter's best friend: Astronomers finds carbon-rich planets could be far more common than previously thought Vast deposits of diamonds and graphite expected to exist on surface Prompts new questions about climate change and how carbon affects our own planet Planets with vast deposits of diamonds and graphite could be commonplace, researchers have claimed. DIAMOND PLANETS Astronomers generally believe that rocky exoplanets are composed - as Earth is - largely of iron, oxygen, magnesium, and silicon, with only a small fraction of carbon. The researchers found that, in disks with carbon-oxygen ratios greater than 0.8, carbon-rich planets can form farther from the center of the disk than previously understood. Previous models predicted carbon-rich planets could only form in disks with carbon-oxygen ratios higher than 0.8.

Astronomers Discover Rich Carbon Chemistry in Protoplanetary Disk Around Young Star An international team of astronomers has used Nasa’s James Webb Space Telescope to study the disk of gas and dust surrounding a young, very low-mass star, revealing the largest number of carbon-containing molecules ever observed in such a disk. It is a very different planet-forming environment than we usually …

10 Billion Earth-Like Planets May Exist in Our Galaxy

Wired  

About 40 percent of red dwarf stars may have Earth-sized planets orbiting them that have the right conditions for life. The new estimate comes from a team of astronomers using the European Southern Observatory's HARPS planet-hunting telescope to look at a sample of 102 nearby red dwarfs over a six-year period. Larger planets, about the size of Jupiter, were found …
