Nearly 90 percent of all-stars are at what point in their life cycles?
Nearly 90 percent of all-stars are in the main-sequence phase of their life cycle. This is when they are fusing hydrogen into helium in their cores, a stable phase that can last for billions of years.
90 percent of the stars are what stars?
90% of the stars in the universe are classified as main sequence stars, which includes stars like our sun. These stars are in the stable phase of their life cycle, converting hydrogen into helium through nuclear fusion in their cores.
Do all stars turn hydrogen in to helium?
No, not all stars turn hydrogen into helium. Stars like our Sun do convert hydrogen into helium through nuclear fusion in their cores. However, more massive stars can undergo further fusion reactions involving helium, producing heavier elements like carbon, oxygen, and even iron.
Do stars reproduce?
No, stars do not reproduce in the same way plants or animals do. Stars form from a process called stellar nucleosynthesis, where elements are fused together in their cores. They do not have the ability to reproduce like living organisms do.
What type of star forms the majority of visible stars in the sky?
The majority of visible stars in the sky are main sequence stars, like our own Sun. These stars are in the stable phase of their life cycle where they are fusing hydrogen into helium in their cores.
Stars that generate energy in their cores are called?
Basically all stars do that.
What is the history of carbonation?
Carbon is formed in the cores of stars and distributed into space during the death of stars.
Where can nuclear fussion be found?
The cores of stars and hydrogen bombs.
Where does nuclear fusion occur and why?
In the cores of stars and hydrogen bombs.
When was oxygen made?
Oxygen is made all the time in the cores of stars.
Where oxygen come from?
Oxygen was created by fusion in the cores of stars and distributed through the universe when those stars exploded.
When was selenium made?
Like most elements, selenium was formed in the cores of stars.
How is gold grown?
Gold is an element that is formed in the cores of stars; it is not organic and does not grow.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
Which stars have convective cores?
Main sequence stars with masses greater than about 1.3 times that of the Sun have convective cores. This includes stars like our Sun and more massive ones. During the main sequence phase, nuclear fusion occurs in the core of these stars, generating energy that drives convection in their interiors.
Do stars ever into black holes?
Yes. When the most massive stars die, their cores collapse to form black holes.
Do stars ever turn into black?
Yes. When the most massive stars die, their cores collapse to form black holes.
