An international team of astronomers has used NASA’s James Webb Space Telescope to study the disk of gas and dust around a young, very low-mass star. The results reveal the largest number of carbon-containing molecules seen to date in such a disk. These findings have implications for the potential composition of any planets that might form around this star.
Rocky planets are more likely than gas giants to form around low-mass stars, making them the most common planets around the most common stars in our galaxy. Little is known about the chemistry of such worlds, which may be similar to or very different from Earth. By studying the disks from which such planets form, astronomers hope to better understand the planet formation process and the compositions of the resulting planets.
Planet-forming disks around very low-mass stars are difficult to study because they are smaller and fainter than disks around high-mass stars. A program called the MIRI (Mid-Infrared Instrument) Mid-INfrared Disk Survey (MINDS) aims to use Webb’s unique capabilities to build a bridge between the chemical inventory of disks and the properties of exoplanets.

This is an artist’s impression of a young star surrounded by a disk of gas and dust. An international team of astronomers has used NASA’s James Webb Space Telescope to study the disk around a young and very low-mass star known as ISO-ChaI 147. The results reveal the richest hydrocarbon chemistry seen to date in a protoplanetary disk. (Photo Creidt: NASA/JPL-Caltech)
