What causes interstellar dust and gas to start to contract and form a protostar?
A protostar forms when gravity pulls the dust and gases in a nebula together.
What is the difference between a nebula and a protostar?
A nebula is a vast cloud of gas and dust in space, while a protostar is a dense region within a nebula where gravity causes material to come together and heat up, eventually leading to the formation of a star. In essence, a protostar is a stage in the formation process of a star within a nebula.
What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
What force causes protostars to form?
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
Is a protostar in energy balance Why or why not?
A protostar is not in energy balance because it is still in the process of accumulating mass and contracting under gravity. This causes the protostar to release energy as it heats up, but it has not yet reached a stable state of equilibrium where the energy being released is balanced by the energy being generated.
What come after a nebula?
After a nebula, the next stage in the life cycle of a star is usually a protostar, where gravity causes the gas and dust within the nebula to begin collapsing and forming a dense core. Following this stage, the protostar may evolve into a main sequence star, where nuclear fusion begins in its core and it enters a stable period of energy production.
What is the definition of a low mass proto star?
a low mass protostar is the begining formation of a low mass star. a low mass protostar is formed by a nebula (stellar nursery), like a cloud in space, where all stares come from. the definition of protostar is: a collection of gas, and dust who`s gravitational pull is causing it to collapse on itself & form a star. a LOW MASS protostar just has a LOWER MASS then a HIGH MASS protostar. Your Welcome:)
What must happen before a protostar will glow?
Before a protostar can start glowing, it must finish collecting enough gas and dust to trigger nuclear fusion in its core. This process requires the protostar to reach a temperature and pressure high enough for hydrogen atoms to fuse together, releasing energy as light and heat.
How many years does it take to produce a star?
Well its a 2 fold answer really. Firstly the gases that form a star take millions if not billions of years to come together. However when a Protostar is formed, this is not a true star as it produces heat via friction not fusion; once this starts to occur it only take about 100,000 years to go from Protostar to Star.
What is a star called before it is born?
A star is called a protostar before it begins nuclear fusion in its core and officially becomes a star. During this stage, a protostar is formed from a collapsing cloud of gas and dust, as gravity pulls material together and heats up the core.
What is a star called that begins as a large cloud of dust and gas?
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
The earliest stage of a stars life is called a?
A Protostar.
