A Star Named 'Nasty'... 1433050102616394

The star known as "Nasty" is an enduring mystery. A resident of our own Milky Way, the aging star is much more massive than our own Sun and operates in a peculiar way: Having quickly burned through its outer hydrogen layers, it's revealed a super-hot, super-bright helium-burning core. It's much, much brighter and hotter than our Sun.

Nasty is categorized as a Wolf-Rayet star, but it features a very significant deviation from other stars of its type. While fitting the category's characteristic spectra—which reveal large amounts of burning helium and relatively tiny amounts of hydrogen—Nasty isn't blasting jets of gas out into space like most of its peers. These jets, which reach velocities of up to 2,400 kilometers per second, are replaced in this case by an enormous gaseous disc nearly two trillion miles across that may be only a few thousand years old. Barely a blink in astro-time.

This disc is interesting because it suggests an alternate origin story for Wolf-Rayets. In the more commonly-accepted explanation, a Wolf-Rayet forms as the massive star begins to swell up near the end of its life, suddenly ejecting its hydrogen cloak. The new model, which is being advanced by a group of astronomers using the Hubble Space Telescope, suggests some interaction with another star, as might occur in a binary star system.

Let see if I understood correctly... Nast1 instead of spreading her gases, has created a disc around it... like Saturn?
