uy scuti planets

Even for a Wolf-Rayet star, WR 102 has intense stellar winds.

After engulfing the innermost planets, possibly including Earth, the Sun will continually shed its outer layers, eventually leaving behind a smoldering white dwarf surrounded by a beautiful planetary nebula of glowing gas. The outer shells of hydrogen around the core get hot enough to begin fusion.

Instead, the bragging rights for the fastest known star (that’s not a white dwarf) belong to a speed demon known as S5-HVS1. I have not seen any indication that UY Scu has planets.

It is also a massive red supergiant and a variable star. Again, it resides in the Milky Way and is located in the constellation Scutum.

If a star is exceptionally massive, it gobbles up its fuel, causing it to live fast and die hard. Astronomers think S5-HVS1 achieved such a breakneck speed following its ejection from a binary system that passed too close to the Milky Way’s central black hole, as seen in this artist’s concept. Detecting such a transit is also the way researchers find many exoplanets. These stellar winds are so powerful — reaching a velocity of around 5.8 million mph (9.4 million km/h) — that by the end of its life, the star is expected to expel enough gas to end up weighing just over 50 solar masses.

(UY Scuti has already shed a lot of mass.)


Based on UY Scuti’s known properties, the star fuses hydrogen around its core and has begun to fuse helium. For UY Scuti, the location is 18h 27m 36.5334 and -12 ° 27` 58.866 . The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. But UY Scuti, located near the center of the Milky Way in the constellation Scutum, is around 1,700 times the Sun’s width.

If you were to fly a Boeing 777 airplane around UY Scuti, it … But later, researchers noticed UY Scuti’s brightness changes over a period of about 740 days, leading them to reclassify it as a variable star.

However, the hottest star, WR 102, is an especially rare WO-type Wolf-Rayet, which is a late-stage star that has a surface heavily enriched with ionized oxygen.

However, that’s still plenty big enough to produce an astounding supernova.
For reference, that’s about 0.6 percent the speed of light. And as long as UY Scuti doesn’t expel too much mass over the course of its remaining life, it will eventually start producing iron. Still burning through the hydrogen in its core, our middle-aged Sun is comfortable at its current, relatively petite size.

Although that may not seem like much for a massive star, keep in mind that at this rate, WR 102 would be completely gone in less than 2 million years. All said, astronomers only know of about 10 WO-type Wolf-Rayet stars in the entire universe.

“Understanding the boundary that separates stars from brown dwarfs will improve our understanding of how both form and evolve,” Serge Dieterich of the Carnegie Institution for Science, an astronomer who studies the smallest stars, said in a statement.

It will eventually become a yellow hypergiant, a Wolf-Rayet star, or …

However, RMC 136a1 is the brightest of these beacons.

However, we never had an unambiguous association of such a fast star with the galactic center,” Sergey Koposov of Carnegie Mellon University, lead author of the study, said in a press release.

Chinese work Tao Te Ching, the gist holds true. In 1860, astronomers at Bonn Observatory in Germany first cataloged UY Scuti as part of a star survey.

UY Scuti is a red supergiant star, which is usually an aging star.

There are generally two ways of finding planets.

Although not well understood, brown dwarfs are not-quite-planets, not-quite-stars whose cores can only fuse a heavy form of hydrogen called deuterium, as well as possibly lithium. “My favorite part of this discovery is thinking about where this star came from and where it’s going,” co-author Alex Ji said. When the stellar pair ventured too close, the black hole captured the companion star, releasing S5-HSV1 from its binary dance and flinging it through space.

In a 2015 paper that explored how much time a variety of WO-type Wolf-Rayets have left before exploding as supernovae, WR 102 was found to have the worst prognosis.

UY Scuti is a reid supergiant starn in the Scutum constellation. However, if a star is small and light, it has a slow metabolism, allowing it to live an extremely long life. But like any red supergiant — including Betelgeuse — UY Scuti is destined to end its life with a bang.

That’s fast, but it’s nothing to crow about.
