Using the James Webb Space Telescope, astronomers have discovered the richest"menu" of hydrocarbons ever seen in a planet-forming disk. This observation, which involved the protoplanetary disk around a tiny star, also revealed the first detection of ethane outside the solar system.. ISO-ChaI 147 is a young star located in the Chameleon I star-forming region of around 237 stars. This region is located around 600 light-years away.
The amount of material in a protoplanetary disk and how that gas and dust is distributed places a limit on how many planets a star can host, as well as what building blocks those planets can be supplied with. The JWST ISO-ChaI 147 results indicate this protoplanetary disk is better suited to birthing smaller rocky planets rather than larger gas giants.
The reason for the carbon and oxygen imbalance between protoplanetary disks of stars with different masses is not currently understood. For instance, it could be the result of disks around smaller stars beingIf the former is true, that would mean carbon enrichment can happen as solid particles in the disk are stripped of their carbon content. That content would be released as gas. These carbon-deprived solid particles would go on to form planets with rocky bodies that are carbon-poor.
