What is the final stage in the life of a sun like star?

What is the final stage in the life of a sun like star?

A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant.

What happens to a Sun sized star at the end of its life cycle?

Small stars, like the Sun, will undergo a relatively peaceful and beautiful death that sees them pass through a planetary nebula phase to become a white dwarf, which eventually cools down over time and stops glowing to become a so-called “black dwarf”.

What is a star called at the end of its life cycle?

A planetary nebula is the remnant of a star like our Sun, when it has reached what can be described as the end of its life.

What happens in the first stage of a star much bigger than the Sun’s death?

Stars More Massive Than the Sun The star collapses by its own gravity and the iron core heats up. The core becomes so tightly packed that protons and electrons merge to form neutrons.

What happens when a star comes to an end?

Most stars take millions of years to die. When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. After puffing off its outer layers, the star collapses to form a very dense white dwarf.

How does the life cycle of a star end?

Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All-stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

Is the Sun in the main sequence stage of its life?

The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.

What happens to the sun during the evolution of a star?

During the Main Sequence lifetime of Sun-like stars, this wind is not very strong—that is, the total amount of mass being lost by the Sun is small. However, during the later phases of a star’s evolution, the mass loss rate associated with the stellar wind can increase significantly.

What happens in the main sequence of a star?

The main sequence phase is the stage in development where the core temperature reaches the point for the fusion to commence. In this process, the protons of hydrogen are converted into atoms of helium. This reaction is exothermic; it gives off more heat than it requires and so the core of a main-sequence star releases a tremendous amount of energy.
