What makes a blue supergiant?

What makes a blue supergiant?

When the star is smaller and more compact, its luminosity is contained over a smaller surface area and so its temperature is much hotter; this is the blue supergiant phase. These stars can then puff up expanding to a much larger size, spreading their luminosity over a much larger area.

What is a blue white supergiant?

A blue supergiant (BSG) is a hot, luminous star, often referred to as an OB supergiant. They are larger than the Sun but smaller than a red supergiant, with surface temperatures of 10,000–50,000 K and luminosities from about 10,000 to a million times that of the Sun.

What is the difference between a blue supergiant and a red giant?

While red supergiants are the largest stars, each with a radius between 200 and 800 times the radius of our Sun, blue supergiants are decidedly smaller. Most are less than 25 solar radii. However, they have been found, in many cases, to be some of the most massive in the universe.

Why are blue supergiants blue?

These stars have surface temperatures of between 20,000 – 50,000°C and appear blue in colour. They are termed ‘blue supergiants’ due to their appearance and the enormous amounts of energy that they can radiate. So much energy is created in the centres of these stars that they are always on the edge of catastrophe.

What color are supergiants?

Red supergiants have the largest radius of all known stars. They have low surface temperatures (for stars!) of below 4,100 K. This causes them to shine with a red colour. The star Betelgeuse in the constellation of Orion is a red supergiant.

How many blue supergiants are there?

Our own Milky Way galaxy contains billions of stars of many different sizes and colors. From cool red dwarves to hot blue supergiants, there are thought to be about 250 billion stars within our galaxy alone. On any given clear night, you might be able to see about 2,000 of them. What colors can you see?

What does a blue supergiant look like?

Blue supergiants are supergiant stars (class I) of spectral type O. They are extremely hot and bright, with surface temperatures of between 20,000 – 50,000 degrees Celsius. The best known example is Rigel, the brightest star in the constellation of Orion.

What star is an example of a blue supergiant?

Rigel
Blue supergiants are supergiant stars (class I) of spectral type O. They are extremely hot and bright, with surface temperatures of between 20,000 – 50,000 degrees Celsius. The best known example is Rigel, the brightest star in the constellation of Orion.

Are blue Giants actually blue?

A blue giant star can put out 10,000 times as much energy as the Sun. The true monsters of the Universe are blue supergiant stars, like Rigel. These can be a blue star with surface temperatures of 20,000 – 50,000 Kelvin and can be 25 times larger than the Sun.

Do blue supergiants have planets?

Blue Supergiants Don’t Have Planets None of them are blue giant stars. Part of the reason is that it takes billions of years for planets to form and, unfortunately, blue giants simply don’t live that long. One, HD 37974 (R126) is over 70 times more massive than the Sun and is over a million times more luminous.

What is the hottest blue supergiant?

What kind of star is a blue supergiant?

Blue stars are categorized as the hottest stars and supergiants are considered the second largest celestial objects, behind hypergiants. It’s shiny variant likely references this. The description of the submission is a reference to the song New Person, Same Old Mistakes by Tame Impala.

What is the multiplier for the blue supergiant?

The Blue Supergiant has a basic multiplier of x3 which can be increased to a x75 when used together with a Nova Star (usually multiplies star-related item multipliers by x4). It also gets a +4x multiplier if used with ores from a Stellarite Mine .

How big are blue supergiant stars in Kelvin?

Blue supergiant stars are amongst the largest and brightest stars in the world. They are characterized by high temperatures ranging from 20,000 – 50,000 kelvin (35,540.3 – 89,540.3 °F). These bright and hot stars are roughly the size of 20 solar masses.

Why are blue giant stars bigger than red giant stars?

Unlike red giant stars that are big because they are swollen, blue giants are big because they contain a lot of material.
