Red super giants are the largest stars in the universe in terms of volume, although they are not the most massive. Red supergiant stars are what become of large stars (stars that are 10 or more times massive than our own) towards the end of their life, once the hydrogen fuel has mostly been exhausted, and the helium burning stage is in effect. These stars are relatively cool, with surface temperatures around 3500-4500 degrees Kelvin, but have huge sizes. The largest known red super giant in the Galaxy is a hyper giant called VY Canis Majoris, which radius is around 1500-2000 times that of our sun. The radius of most red giants is between 200 and 800 times that of the sun. If this largest known star were in our solar system, then its surface would extend out further than Jupiter's orbit, maybe even approaching Saturn's orbit.
What else can I help you with?
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
Can red supergiants become black holes?
Red super-giants form when stars of more than ten solar masses begin to burn their helium. Eventually such a star will burn all of possible fuels and go into gravitational collapse, resulting in a super-nova. If the mass left over from this collapse is large enough (a remnant of three to five solar masses), the remnant will collapse into a black hole.
What are the three extra groups of the H-R diagram?
The three extra groups on the H-R diagram are white dwarfs, red giants, and supergiants. These groups represent stars in different stages of their evolution based on their luminosity and temperature. White dwarfs are small, hot stars near the end of their life cycle, red giants are large, cool stars in the later stages of their life cycle, and supergiants are massive, luminous stars.
What cool and bright stars are located in the upper right of the H-R diagram?
In the usual position of the axes, the upper-right is populated by giants and supergiants.
What are the universe's biggest stars?
Red supergiants
What stars are extremely luminous but not hot?
Red giants, red supergiants.
Which star is likey a super giant?
The stars that are like supergiants are called "red giants" or "red supergiants".
Are the largest stars known red super giants?
No, the largest star known is a Red Hypergiant (vy canis majoris) which are much larger than supergiants. Most of the largest stars are red hypergiants followed by red supergiants.
What type of stars are Betelgeuese and Antares?
Both are red supergiants.
What are larger and more luminous than red giants?
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.
What are the name of red supergiants star?
The five largest known red supergiants in the Galaxy are VY Canis Majoris, VV Cephei A, V354 Cephei, RW Cephei and KW Sagittarii.
How long do red supergiants live?
Red supergiants have relatively short lifespans compared to other stars, typically a few million years. They spend only a few hundred thousand years in the red supergiant phase before eventually evolving into supernovae or collapsing into black holes.
What temperature do blue to red supergiants?
blue and red supergiant temparutes are 10000000000000 degrees celsius
What is the Coolest largest and brightest than most main sequence stars?
Red giants, red supergiants and red hypergiants.
Where are white dwarfs supeegiants and red giants?
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
Would the surface temperature of white dwarfs stars be higher or lower than red supergiants?
The surface temperature of white dwarf stars is generally higher than that of red supergiants. White dwarfs typically have temperatures ranging from about 5,000 to 100,000 Kelvin, while red supergiants usually have surface temperatures between 3,000 and 4,500 Kelvin. This significant difference is due to the evolutionary stages these stars occupy, with white dwarfs being the remnants of stars that have exhausted their nuclear fuel, while red supergiants are in a later phase of stellar evolution.
