What else can I help you with?
What does a blue giant star and the sun have in common?
They are both stars which are undergoing a process of thermonuclear fusion.
What changes a protostar to a a full fledged star?
thermonuclear fusion
What is inside of the star?
In main sequence stars, it is thermonuclear fusion of hydrogen into helium.
What determines if n object in outer space is a Planet?
A planet is a celestial body which orbits a star, a planet must be large enough for it's own gravity to create it's spherical shape but not too large that it undergoes thermonuclear fusion (thermonuclear fusion is the process of star becoming a star due to it's size) there are many other factors but that was a basic answer.
How does a mian sequnce star generates energy?
By nuclear fusion - converting hydrogen-1 into helium-4.
How does thermonuclear fusion contribute to the process of helium burning in a star?
Thermonuclear fusion in stars is the process where hydrogen atoms combine to form helium, releasing a lot of energy in the process. This fusion reaction is what powers the star and allows it to shine. In the process of helium burning, helium atoms fuse together to form heavier elements like carbon and oxygen. This process also releases energy and helps sustain the star's energy production.
What is the principal source of stellar energy?
The principal source of stellar energy is nuclear fusion, where hydrogen atoms combine to form helium in the core of a star. This process releases immense amounts of energy in the form of light and heat.
What difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct fusion.
What is the role of gravity in the life cycle of a star?
Gravity is responsible for the collapse of a stellar nebula into something which is dense enough for sustained thermonuclear fusion of hydrogen atoms into helium can begin. The fusion process generates radiation pressure which acts outwards and gravity is required to act against that force.
When does a protostar become a star?
The basic idea is that the protostar contracts, under the influence of gravity, until it gets dense and hot enough to undergo nuclear fusion. You can find more details at the Wikipedia article "Protostar".
What process powers a star?
nuclear fusion
Fusion of hydrogen to helium occurs in?
The fusion of hydrogen to helium occurs at the core of stars, such as our Sun. This process releases large amounts of energy in the form of light and heat, which powers the star and sustains its stability. It is through this fusion reaction that stars shine and provide heat and light to their surrounding systems.
