An article published in the journal “Nature Astronomy” reports the observation of 17 dust rings around WR 140, a so-called Wolf-Rayet star that has a very young and massive companion. A team of researchers used the James Webb Space Telescope’s MIRI instrument to study the area around this pair of stars, obtaining results far superior to those of other instruments, which had only identified two rings. According to the researchers, the rings are generated when the two stars get closer and their stellar winds interact violently causing the gas to compress, as it also contains elements heavier than hydrogen and allows it to form dust.
