Is WOH G64 the biggest star?

Is WOH G64 the biggest star?

Another hypergiant star is WOH G64, also in the Large Magellanic Cloud, and thus located at a distance of some 168,000 light years from Earth. At an estimated 1,540 times the sun’s radius, this star is thought to be the largest star in the Large Magellanic Cloud, in terms of sheer physical size.

Does WOH G64 have planets?

WOH G64’s stellar wind and low density has made a massive donut-shaped cloud that weighs in at 6.25x the weight of our Sun and 0.4744 light-years across. It may be great for forming planets, but no planet has been discovered.

What is the luminosity of WOH G64?

WOH G64

Observation data Epoch J2000.0 Equinox J2000.0

How many solar masses is WOH G64?

The results of interferometric observations with ESO’s Very Large Telescope Interferometer (VLTI), published in 2008, revealed that WOH G64 is surrounded by an optically thick torus which appears almost pole-on. The results were consistent with an initial mass of 25 solar masses.

What is biggest star in the universe?

The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.

What color is a red supergiant?

Red supergiants look red because of their low surface temperatures. They range from about 3,500 – 4,500 Kelvin. According to Wien’s law, the color at which a star radiates most strongly is directly related to its surface temperature.

Will a 30 solar mass star supernova?

One option is that a very massive star (more than 30 solar masses, possibly up to 150 solar masses) that had been previously losing mass eventually collapses in on itself, causes a massive explosion and eventually forms a black hole.

How big is WOH G64 in light years?

Based on the spectral type (M5I) of the star, the star’s colour is red . The star can not be seen by the naked eye, you need a telescope to see it. WOH G64 has a radius that is 1,540.00 times bigger than the Suns. The star is calculated at being about -14305.41 light years away from us.

What kind of star is the WOH G64 star?

WOH G64 ( IRAS 04553-6825) is a red hypergiant (RHG) or red supergiant (RSG) star in the Large Magellanic Cloud (LMC) satellite galaxy in the southern constellation of Dorado.

What kind of emission does WOH G64 have?

WOH G64 was also discovered to be a well-known source of OH, H 2O, and SiO masers emission, which is typical of an OH/IR supergiant star. It also shows an unusual spectrum of nebular emission; the hot gas is rich in nitrogen and has a radial velocity considerably more positive than that of the star.

How big is the envelope of WOH G64?

WOH G64 is surrounded by a thick envelope of dust about a light year across. The envelope consists of material expelled from the star. WOH G64 has so far expelled between 3 and 9 solar masses of material – between a tenth and a third of its initial mass – through a strong stellar wind. The star WOH G64.
