The existence of these shells is not mysterious and it is understood how they are produced periodically approximately every 7.94 years. About 20 rings are visible, and according to astrophysicists, the youngest was born in 2016. But how do they know?
This animation shows dust production in the WR 140 binary star system as the Wolf-Rayet star’s orbit approaches the O-type star and their stellar winds collide. Stronger winds from the Wolf-Rayet star blow behind the O star, forming dust in their wake as the mixed stellar material cools. As the process is repeated, the powder will form a layer. © NASA, ESA and J. Olmsted (STScI)
The determination of the orbital parameters of the stars of WR 140 shows that they are in respective orbits quiteso that they approach in a consistent manner, reaching for one of them their (the shortest distance between them) approximately every 7.94 years precisely.
The collision between the stellar winds produced by the two stars is quite violent at this time, and an expanding bubble of matter is born which, as it cools, will cause the dust to condense. It is this dust that is heated by radiationof the two massive young stars will cool by radiating in the infrared, revealing the expanding shells to the JWST. So we can see a kind of giving testimony of the past history during some 160 years of the binary.
