A star starts as a blue giant, then becomes a yellow dwarf. It will then swell into a red giant. Then, at the end of it's life, it becomes a super giant and explodes. The remains are usually a red dwarf, which brightens and becomes a white dwarf. The white dwarf fades and becomes a black dwarf which turns to dust. Sometimes after a supernova it turns into a pulsar, which rotates 300-1,000 times a minute and makes giant rhythmic pulses that stretch for light years.

Most stars are what kind of stars?
Most stars in the universe are main sequence stars. These stars are in a stable phase of their life cycle where they generate energy through nuclear fusion in their cores. The Sun is a main sequence star.
Are most stars main sequence stars?
yes
How many years do spectral class O5 stars remain on the main sequence?
Spectral class O5 stars remain on the main sequence for around 3-4 million years before they evolve off the main sequence stage. These stars have extremely high luminosities and temperatures, leading to a short main sequence lifetime compared to lower mass stars.
What sequence of stars is listed in order of increasing luminosity?
The sequence of stars listed in order of increasing luminosity typically includes red dwarfs, main-sequence stars (like our Sun), giant stars, and supergiant stars. Red dwarfs are the least luminous, followed by main-sequence stars, then giant stars, and finally supergiants, which are the most luminous. This order reflects the increasing energy output and size of the stars as they evolve.
A diagonal pattern on an H-R diagram where most stars lie is called?
The diagonal pattern on an H-R diagram where most stars lie is called the main sequence. This is where stars are fusing hydrogen into helium in their cores, representing the stable phase of a star's life cycle. The main sequence is a fundamental feature of stellar evolution and provides insight into a star's mass, luminosity, and temperature.
What is a stars longest point of its life?
Main sequence
What is the step after main sequence in a stars life?
After the main sequence, a star becomes a red giant.
What state do stars spend most of their life cycle?
The main sequence.
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.
Are most stars in our galaxy found in the main sequence?
Yes, the majority of stars in our galaxy, including our Sun, are found in the main sequence stage of their life cycle. The main sequence is a phase where stars are fusing hydrogen into helium in their cores, which is the most common stage of stellar evolution.
What does a main sequence do?
A main sequence does not do anything - it is just a name for a period in a stars life. [See related question]
Most stars are classified as which of these?
Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.
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.
Is most stars sequence stars?
"main sequence" is the tern.
About 90 percent of the stars including the sun are what stars?
About 90 percent of the stars, including the sun, are main sequence stars. This means they are in a stable phase of their life cycle, converting hydrogen into helium through nuclear fusion in their cores.
What are the main sequence stars life?
Understand that the Main Sequence is not a place or a category that a star belongs to all its life. A star's destiny is controlled by its size and this determines how much time it spends on the Main Sequence.
Do main sequence stars have a shorter life cycle than other stars do?
All stars that are converting hydrogen into helium via nuclear fusion are said to be on "main-sequence". See related question for more information
