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.
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.
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.
The matter from a nebula that has begun to condense under gravity to form a star is called a protostar. As gravity causes the protostar to contract, the core temperatures rise until nuclear fusion ignites, and a star is born. This marks the transition from a cloud of gas and dust to a shining star.

protostar or nebula
The nebula forms into a protostar.

a protostar
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
The formation of a protostar from a nebula. As the protostar forms, it accretes more mass from the cloud and spins. As it gains more mass, it eventually becomes massive enough to ignite the core and become a star. The protostar is the first step in the evolution of any star.
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.
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.
