Why are White Dwarf stars so dim?
White dwarfs are dim because they are small, and small stars radiate less light.
What are the two major energies released from stars?
heat and light.
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
Why are dwarf stars hard to find?
Dwarf stars are small and give of very little light. Which is what makes them so hard to find.
Is the energy released by the stars a result of fission reactions?
No. However, the stars do use a different form of nuclear energy, called nuclear fusion or fusion.In fission, heavy elements such as uranium are broken down into smaller elements, releasing huge amounts of energy in the process. This is used in power plants on Earth and was used in the first nuclear bomb dropped on Hiroshima, Japan.In fusion, however, light elements starting with Hydrogen, the most abundant element in the Universe, are actually fused together into heavier elements such as Helium. Stars use this because there is SO much Hydrogen in the universe, and stars are full of it. Fusion requires a tremendous amount of energy to kick-start, but in return an even more tremendous amount of energy is released. That is what powers the stars. Currently, it is believed that elements up to oxygen (8) exist in our Sun.
How did nuclear fussion in stars help create the elements?
Light elements combined to form the heavier elements.
Small stars create small elements why?
Elements are the same size regardless of how they are synthesized. It is true, however, that small stars create fewer elements, and that the elements they create are lighter. A normal G-type star can, during the course of its evolution along the Main Sequence, produce elements up to iron. For elements heavier than that, larger stars are required; when they go nova, they can produce elements as heavy as uranium and beyond.
Why do scientists believe that stars contain the same elements as the solar system?
The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.
What does some of the light that radiates from a star do?
Is absorbed by elements in a stars atmosphere
Which of these elements does this star contain?
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
How can stars give off their own light?
stars turn hydrogen into heavier elements in nuclear fusion. this process gives off light and heat.
Where in the universe are heavy elements made?
Light elements are made in light weight stars via stellar nucleosynthesis. Elements as heavy as iron form in the cores of massive stars. Anything heavier than iron requires a supernova--the collapse and explosion of a super massive star.
Can light from stars be turned into energy?
Light from the stars is energy. However, the amount of energy that this light accounts for is too small to be of any use.
Do the stars reflect light or give out light?
Stars give out light. The sun is a relatively small star but it's a a lot close than the others making it appear bigger. Stars are explosions and give out light.
Why are White Dwarf stars so dim?
White dwarfs are dim because they are small, and small stars radiate less light.
How stars differ as to brightness?
every star has different elements in the atmosphere which absorbs the light
What are the release dates for The Light of Western Stars - 1940?
The Light of Western Stars - 1940 was released on: USA: 17 April 1940
