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.

Un articolo pubblicato sulla rivista "Nature Astronomy" riporta l'osservazione di ben 17 anelli di polvere attorno a WR 140, una cosiddetta stella di Wolf-Rayet che ha una compagna molto giovane e massiccia. Un team di ricercatori ha usato lo strumento MIRI del telescopio spaziale James Webb per studiare l'area attorno a questa coppia di stelle ottenendo risultati molto superiori a quelli di altri strumenti, che avevano individuato solo due anelli. Secondo i ricercatori, gli anelli vengono generati quando le due stelle sono più vicine e i loro venti stellari interagiscono violentemente causando la compressione del gas, che contiene anche elementi più pesanti dell'idrogeno e permette di formare polveri.
