What happen in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
A star is not considered born until the process of begins?
A star is considered born when nuclear fusion begins in its core, creating energy and light. This process marks the transition from a protostar to a true star.
When does hydrogen first begin to fuse into helium in the star formation process?
Hydrogen fusion into helium typically begins within a star when the core temperature reaches about 10 million degrees Celsius, which is necessary to overcome the electrostatic repulsion between hydrogen nuclei. This process marks the birth of a star's main sequence phase, where hydrogen fusion is the primary energy source.
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.
How isa black hole form?
A black hole forms when a massive star collapses under its own gravity after running out of nuclear fuel. This collapse causes the star to explode in a supernova and the remaining core implodes, forming a singularity with infinite density and gravity, surrounded by an event horizon from which nothing can escape, including light. This marks the birth of a black hole.

What marks Jesus's birth place?
a star
What event marks the birth of a star?
fusion of hydrogen atoms into helium atoms
What event marks a birth of a star?
fusion of hydrogen atoms into helium atoms
What is a star birth?
A star birth refers to the formation of a new star from a collapsing cloud of gas and dust in space. As gravity causes the cloud to contract, the core temperature rises until nuclear fusion is ignited, marking the birth of a star. These new stars eventually stabilize and begin to generate energy through nuclear reactions in their cores.
A star is not considered born until the process of begins?
A star is considered born when nuclear fusion begins in its core, creating energy and light. This process marks the transition from a protostar to a true star.
Which event marks the beginning of a type II supernova?
The collapse of the star's core is the event that marks the beginning of a type II supernova. This collapse leads to the rapid release of energy, causing the outer layers of the star to be expelled in a violent explosion.
When does hydrogen first begin to fuse into helium in the star formation process?
Hydrogen fusion into helium typically begins within a star when the core temperature reaches about 10 million degrees Celsius, which is necessary to overcome the electrostatic repulsion between hydrogen nuclei. This process marks the birth of a star's main sequence phase, where hydrogen fusion is the primary energy source.
In which part of a newborn star does the fusion reactio occur?
In a newborn star, the fusion reactions occur primarily in its core, where the temperature and pressure are high enough to trigger nuclear fusion. This process generates the energy that powers the star and allows it to shine bright.
What may be formed with the birth of a star?
When a star is born, it can lead to the formation of a solar system with planets, moons, and other celestial bodies. The star itself is a hot, luminous sphere of plasma fueled by nuclear fusion in its core. Additionally, the birth of a star can trigger the creation of nebulae and star clusters in its vicinity.
Where do stars begin their lives?
Stars begin their lives as clouds of gas and dust called nebulae. Within these nebulae, gravity causes the gas and dust to collapse and heat up, eventually leading to the ignition of nuclear fusion in the core, which marks the birth of a star.
