What else can I help you with?
When a protostar rises to 10000000 degrees celsius will a protostar become a star before or after nuclear fusion?
A protostar must reach about 10 million degrees Celsius for nuclear fusion to start in its core, triggering the transition into a true star. This marks the point where hydrogen atoms begin fusing into helium, releasing energy in the process. So, a protostar will become a full-fledged star after nuclear fusion begins at this temperature.
What is it called when a star forms inside a cloud of gas and dust?
It is called stellar birth or star formation. Gravitational forces cause the cloud to collapse, leading to the formation of a protostar that eventually ignites nuclear fusion to become a full-fledged star.
What is a new star called?
A newly formed star is called a protostar. This is the early stage of a star's life cycle when it is still accumulating mass from its surrounding gas and dust. Once a protostar reaches a critical mass and temperature, nuclear fusion begins and it becomes a fully-fledged star.
How do stars form in the universe?
Stars form in the universe through the process of gravitational collapse of gas and dust within interstellar clouds. As the cloud collapses, it heats up and forms a protostar, which eventually ignites nuclear fusion in its core, becoming a full-fledged star.
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
What is the first stage in a star's life cycle?
The first stage in a star's life cycle is the nebula stage, where a cloud of gas and dust in space begins to collapse under its own gravity. This collapse leads to the formation of a protostar, which will eventually become a full-fledged star through nuclear fusion.
What happens after a nebula contracts and its temperature increases to 10million K?
After a nebula contracts and its temperature increases to 10 million K, it can start nuclear fusion in its core, becoming a protostar. The increase in temperature and pressure triggers the fusion of hydrogen atoms into helium atoms, releasing energy in the form of light and heat. The protostar will continue to evolve and eventually become a full-fledged star.
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
What is baby star?
A baby star is a newborn star. It is called "protostar."
What is a star called before it is a star?
A star that is forming is called a protostar.
What is the name of a forming star?
Protostar
How do scientists think that stars were formed?
Scientists believe that stars form from clouds of gas and dust in space, called nebulae. When these clouds become dense enough, gravity causes them to collapse and form a protostar. As the protostar gathers more material, its temperature and pressure increase until nuclear fusion ignites, turning it into a full-fledged star.
