Here is an answer based on a typical star like our Sun. It's slightly simplified.
If you need more detail Wikipedia's "Stellar Evolution" is useful, but a bit complicated.
An easier introduction is given by NASA in the "Sources and related links" below. Just click on that link if you wish.
All stars will eventually exhaust their supply of hydrogen, the main fuel of every star in the universe (and most abundant element in the universe). The main process of fusion that powers all stars converts hydrogen into the heavier element helium (see "fusion" for more details).
For a star with the mass of our Sun, each second millions of tons of hydrogen (600 million) are converted to helium, slowly depleting the remaining hydrogen (our Sun started with about 11-13 billion years of hydrogen "fuel").
When the hydrogen supply runs low, the Sun will expand, reaching the "red giant" stage of its life.
Eventually the core will become hot enough to fuse helium. The process of fusion will then continue with the helium, along with some remaining hydrogen.
The helium will be converted to carbon, continuing to power the star.
A quite complicated situation arises with hydrogen and helium "burning" at different levels in the star.
Fusion stops after producing oxygen nuclei, because the Sun's temperatures will not be high enough to produce heavier elements.
As the last fuel is exhausted, the star's outer layers will be expelled by the imbalance in pressure from fusion versus the gravity holding the star together. As these outer layers are expelled, the core of carbon and oxygen nuclei will be the remnant, a white dwarf star.
In the beginning there will be a super hot white dwarf emitting light until it cools down and no longer emits light and becomes a black dwarf.
High mass stars, after going supernova, become neutron stars or become black holes, if they're massive enough.

What did World events in the late summer and fall of 1949 caused?
In the late summer and fall of 1949, significant world events included the successful detonation of the Soviet atomic bomb in September and the establishment of the People's Republic of China in October. These developments heightened tensions in the Cold War, as they marked the beginning of the nuclear arms race and solidified the division between communist and capitalist blocs. The geopolitical landscape shifted dramatically, leading to increased military alliances and strategies in the West, particularly the formation of NATO in 1949. These events set the stage for further global conflicts and ideological confrontations in the following decades.
What episode does Alison come back on in pretty little liars?
Alison DiLaurentis returns in "Pretty Little Liars" during Season 2, Episode 13, titled "The First Secret." Her return marks a significant moment in the series as it reveals more about her mysterious past and the events leading up to her disappearance. This episode delves into the secrets surrounding her character and sets the stage for many future plot developments.
What is the difference between single stage and multi stage amplifiers?
single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
What are some similarities between a thrust stage and an arena stage?
An arena stage is a theater stage surrounded or nearly surrounded by the audience and a thrust stage is a a stage that projects beyond the proscenium so that the audience sits around the projection.One side of the arena stage does not have the audience and on the trust stage every side of it is covered.
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
True or false. our sun is a white dwarf star?
False. The sun is a yellow main sequence star.
What is the final stage of the yellow stars?
Assuming you mean a "main sequence" yellow star, it's a white dwarf star. In the end that fades to a black dwarf.
What stage of stellar evolution is the sun experiencing at this time?
Our Sun is currently on the Main Sequence stage of it's evolution.
What are the stages of the sun's life cycle?
The sun's life cycle includes the stages of formation, main-sequence, red giant, and white dwarf. It is currently in the main-sequence stage, where it fuses hydrogen into helium in its core. Eventually, it will expand into a red giant before shedding its outer layers and becoming a white dwarf.
What exactly is a white dwarf star?
It is when the star is close to its death stage. {Main Sequence, Giant, Super Giant, and then the white dwarfs}
What stage is our sun in right now?
Our sun is a main sequence (dwarf) star. It's expected to remain so for the next 5 billion years or so. After that it will expand briefly into a red giant, then collapse into a white dwarf.
What stage follows the white dwarf stage of star development red giant prostar neutron black dwarf?
The Neutron stage follows the White Dwarf stage of star development.
How would you arrange this in order red giant white dwarf and main sequence and why?
The order of stellar evolution is typically: main sequence, red giant, and then white dwarf. Stars spend the majority of their life on the main sequence, where they fuse hydrogen into helium. As they exhaust their hydrogen, they expand into red giants. After shedding their outer layers, the remaining core becomes a white dwarf, which is the final stage of a low to medium mass star.
What is the final stage of a yellow star?
The final stage of a yellow star like our Sun is the formation of a planetary nebula. This occurs when the star sheds its outer layers into space, leaving behind a hot core called a white dwarf. Over time, the white dwarf will cool and fade away.
What stage is next when the sun finishes the main sequence stage?
When the Sun exhausts its hydrogen fuel in the core and finishes the main sequence stage, it will enter the red giant phase. During this stage, the core will contract and heat up, causing the outer layers to expand significantly. Eventually, the Sun will shed its outer layers, creating a planetary nebula, while the core will remain as a white dwarf.
What is the next stage after The white dwarf stage?
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
