What else can I help you with?
What is a star like object that generates energy at a high rate?
A star.
How does the protostar stage of a star's life cycle compare with the main-sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
A main sequence star generates energy by fusing what?
Hydrogen
How does the protostar stage of a stars life cycle compare with the main sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
What is a very bright star like object that generates immense energy?
A supernova explosion releases greatly more energy than our Sun in its entire lifetime.
What does it mean for a star to be in the main sequnce?
1) It means that its location on the H-R diagram is along a certain curve; the curve which contains most stars. 2) This, in turn, is a result of the fact that the star currently gets most of its energy by fusing hydrogen-1 into helium-4.
Which two processes can generate energy to help a star maintain its internal thermal pressure?
Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.
What is a large ball of gas that generates its own energy called?
A large ball of gas that generates its own energy is called a star. Stars achieve this by undergoing nuclear fusion reactions in their cores, converting hydrogen into helium and releasing tremendous amounts of energy in the process.
What provides the energy for support of a Horizontal Branch star?
A Horizontal Branch star generates energy through the fusion of helium into carbon and oxygen in its core. This fusion process releases energy in the form of light and heat, which provides the necessary support to balance the star against gravitational collapse.
Is the sun is a planet?
No, the sun is not a planet. It is a star, specifically a medium-sized main sequence star that generates energy through nuclear fusion in its core. Planets orbit stars, including our sun.
What are characteristic of star?
It shines (it generates light).
Does a red dwarf generate a lot of energy?
It depends on what you consider to be a lot of energy. A red dwarf generates far less energy than other classes of star, but still far more than anything on Earth.
