What else can I help you with?
What are the universe's biggest stars?
Red supergiants
Stars much larger then are sun called?
Giants or supergiants
What type of stars are Betelgeuese and Antares?
Both are red supergiants.
What are the biggest and brightest stars called?
The biggest and brightest stars are called supergiants. These stars are much larger, hotter, and more luminous than our Sun. Examples of supergiants include Betelgeuse and Rigel in the constellation Orion.
What stars are extremely luminous but not hot?
Red giants, red supergiants.
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
Can you unscramble staruepings?
The anagram is the word "supergiants" (refers to very large stars).
How big are blue supergiants?
Blue supergiants are among the most massive and luminous stars in the Universe. They can be up to 20 times more massive than the Sun and have radii several hundred times larger. These stars are relatively rare compared to other types of stars.
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.
Do low mass main sequence stars become red super giants?
No. Only massive stars can become supergiants.
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.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
