When does a newly forming star have the greatest luminosity?
A rotating nebula (a cloud of gas and dust) collapses under gravity. This creates a lot of heat energy. A "protostar" forms, before nuclear fusion begins. When the core temperature is high enough, hydrogen nuclei can undergo fusion and become helium, releasing nuclear energy. So, eventually the protostar becomes a "true" star and reaches the Main Sequence on the HR diagram. The newly forming star has its greatest luminosity during the earlyprotostar stage. (The protostar has a much bigger surface area than the final star.)
What does proto mean in protostar?
Wiktionary: "Prototypical; preceding the proper beginning of something". That sounds about right, for a protostar.
What kind of nebula is the eye of god?
The eye of god is a Helix nebula. Close to a Planetary nebula.
What do you call a cloud of dust particles where a star is born?
It is called a Nebula (nebulae for plural). no sorry but your wrong it is a coma It can be both it just depends. The question needs to be more specific
Is the ring nebula a cloud?
The Ring Nebula is classified as a planetary nebula which is a shell of gas and plasma, formed when certain stars die.So, in a way they are clouds of matter in space.
What is it called when the nebula begins collapsing and turning into a small spinning cloud?
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
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 force that turns a nebula into a protostar?
The force that turns a nebula into a protostar is gravity. As regions within a nebula become denser due to slight fluctuations in density, gravity pulls the surrounding gas and dust inward, causing the material to clump together. This process leads to the formation of a protostar as the collapsing material heats up and begins to accumulate mass. Once the temperature and pressure in the core become sufficient to initiate nuclear fusion, the protostar evolves into a main-sequence star.
Another name for the interstellar matter that will eventually form a star is?
protostar or nebula
What do nebulas form?
The nebula forms into a protostar.
What is considered the center of the Orion nebula?
the protostar
What is most likely to be found in a nebula?
a protostar
What happened when the gas in the nebula's center stopped collapsing?
When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
Why doesnt a protostar form a black hole?
The pressure within a protostar counters gravity and prevents the star from collapsing further.
What works with pressure to keep a nebula from collapsing?
The pressure caused by the thermal energy of the gas within the nebula pushes outward in all directions, preventing the nebula from collapsing under its own gravity. This pressure acts to counterbalance the force of gravity, maintaining the nebula's size and structure.
Why did the nebula's condense to form the sun?
If the nebula is gravitationally unstable, it collapsing & forming stars!
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.
