How does a blue star compare to the sun?

Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.

What is the life cycle of a giant blue star?

A middle-sized star like our Sun might last for 12 billion years, while a blue supergiant will detonate with a few hundred million years. The smaller stars will leave neutron stars or black holes behind, while the largest will just vaporize themselves completely.

What are the two different life cycles of stars?

Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

What is the life cycle of a star bigger than the sun?

A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different.

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

Essentially, the differences between a blue giant and a red giant are the age of the stars and their permanence. No blue giant remains a blue giant; it eventually will turn into a red giant.

How hot is a blue giant star?

between 20,000 – 50,000 degrees Celsius
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.

Can blue stars turn red?

Blue giant stars are very hot, with surface temperatures of 20,000-50,000 Kelvin. Blue supergiants can turn into red supergiants and vice versa. 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.

What comes from giant or massive stars?

Super-giant come from giant or massive stars. They grow to as much as three times the mass of our sun as they lose the nuclear fuel at their core.

What are the stages of the sun’s life cycle?

The Sun’s lifecycle is nebula, main sequence star, red giant, white dwarf.

What is the life cycle of the sun?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.
