Just a star. Some have names like Sirius, others have numbers or Greek letters within their constellation like 61 Cygni or Zeta Ursae Majoris, and still others just have catalogue numbers like HD 30187 in the famous Henry Draper catalogue.
A Main Sequence star.
A Main Sequence star.
Once a star is fully formed, it typically becomes a main sequence star. During this stage, it fuses hydrogen into helium in its core, producing energy that allows it to shine steadily for billions of years. The exact characteristics of the main sequence star, such as its size and temperature, depend on its initial mass. After exhausting its hydrogen fuel, the star will evolve into later stages, such as a red giant or supergiant, depending on its mass.
Once a star is fully formed, it typically becomes a main sequence star, where it spends the majority of its life fusing hydrogen into helium in its core. During this phase, it achieves a stable balance between gravitational forces pulling inward and the pressure from nuclear fusion pushing outward. The star will remain in the main sequence phase for millions to billions of years, depending on its mass. Eventually, it will evolve into a red giant, supergiant, or a smaller star, depending on its initial mass.
Not fully developed is partial formed.
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.
A Neutron Star
She was born fully grown.Aphrodite had no childhood, she emerged fully formed and adult from the sea.
The glomerular capsule does not contain fully-formed urine.
Depending on the size of the star: a neutron star or a black hole-
black holes can be formed in a supernova explosion if the mass of the star is largeenoughusually they are created when a massive and dense star like a neutron star collapses
A protostar does not have a fixed temperature in degrees like a fully formed star. It is in the process of forming and can have a range of temperatures depending on its size, mass, and stage of development.
