| 説明 | Tiny star, big potential.Webb studied the planet-forming disk around a star weighing one-tenth of our Sun, finding it to hold the largest number of carbon-containing molecules seen to date in such a disk. These molecules include the first detection of ethane outside of our solar system, as well as ethylene, propyne, and more.Rocky planets are more likely than gas giants to form around low-mass stars, making the planet-forming disks of low-mass stars particularly interesting.

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.The science team explored the region around ISO-ChaI 147, a very low-mass star of 0.11 solar masses. They found that the gas in the planet-forming region of the star is rich in carbon. This could mean that the building blocks for planets may lack carbon because all of the carbon-containing chemicals have evaporated and been lost into the surrounding gas. As a result, any rocky planets that form might be carbon-poor.Image credit: Illustration: NASA-JPLImage Description: A yellow star is at the center, surrounded by a mottled disk of gas and dust that transitions from bright yellow to darker orange moving outward. There is a gap between the inner disk and the star, with two curving streams of gas connecting the star and the disk. The wide disk stretches from about 8 o’clock to 2 o’clock and is tilted so that the nearer side is toward the viewer. A label at lower right says “artist’s concept.” |
