What is the difference between a red and a blue star?
A red star is fusing mostly hydrogen while a blue star has depleted its hydrogen supply and is fusing helium into heavier elements.
A star located off the main sequence indicates what?
That the star has stopped fusing hydrogen in its core as its energy source.
How do stars begin to shine?
After stars are created in nebulae with dust and gas, they can begin the process of fusing hydrogen to make helium. Voila!, one star coming up!
What is a middle age star?
yes, the sun is a middle age star. The age of the sun is found to be 5 billion years. this can be explained very easily. sun is a composition of hydrogen and helium . based on the amount of the hydrogen and the helium the age of the sun has been calculated.
What are the main elements that make up a star?
For main sequence stars, the vast majority is hydrogen and helium. Older stars will exhaust these lighter elements near their cores and begin fusing heavier elements.
How does a main sequence star power itself?
A main sequence star gets its energy by fusing hydrogen-1 into helium-4.
What is the difference between a red and a blue star?
A red star is fusing mostly hydrogen while a blue star has depleted its hydrogen supply and is fusing helium into heavier elements.
What is the defeniton of main sequence star?
A star that is mainly fusing hydrogen into helium.
A main sequence star generates energy by fusing what?
Hydrogen
Is a star born when helium and oxygen combine?
No. A star is born when hydrogen stars fusing.
Do hydrogen make stars?
technically speaking, stars are first made of Hydrogen. The moment the star comes to life, it starts fusing together Hydrogen atoms, forming helium. when a star is nearing the end of its life, it starts fusing together helium and keeps on fusing until there is nothing more to fuse. then, the star dies.
What is life stage of life of the star Alrisha?
Alrisha, also known as Alpha Piscium, is a binary star system located in the constellation Pisces. It is a main sequence star, meaning it is currently in the stage where it is fusing hydrogen into helium in its core, emitting energy in the form of light and heat. This stage of a star's life can last for billions of years.
What is the main activity of a sequence star?
The activity is -fusing hydrogen into helium.
How is energy created in a star?
Nuclear fusion - fusing hydrogen-1 into helium-4.
A star located off the main sequence indicates what?
That the star has stopped fusing hydrogen in its core as its energy source.
What chemical element is the primary constitutent of a young star?
In the current stage of the Universe, stars start off with lots of hydrogen-1 - and that's what they first fuse, since fusing heavier elements requires higher temperatures.Actually, hydrogen-2 (also known as deuterium) is even easier to fuse, but stars don't have significant amounts of that.
What types of stars are main sequence stars?
Any star that it fusing hydrogen into helium is classed as a main sequence star.
