In a new study, this team explored the region around a very low-mass star known as ISO-ChaI 147, a 1 to 2 million-year-old star that weighs just 0.11 times as much as the Sun. The spectrum revealed by Webb’s MIRI shows the richest hydrocarbon chemistry seen to date in a protoplanetary disk – a total of 13 different carbon-bearing molecules. The team’s findings include the first detection of ethane (C2H6) outside of our solar system, as well as ethylene (C2H4), propyne (C3H4), and the methyl radical CH3.
