The main sequence of stars is called the "main sequence" itself. It is a continuous and distinctive band on the Hertzsprung-Russell diagram where stars spend most of their lifetime, fusing hydrogen into helium in their cores. Main sequence stars vary in size, temperature, and luminosity, ranging from hot, massive O-type stars to cooler, smaller M-type stars. This stage represents a significant phase in stellar evolution before stars evolve into red giants or other end states.
What else can I help you with?
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.
Are most stars main sequence stars?
yes
What is the main sequence temperature?
The temperature of main sequence stars can vary quite a bit.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The lower right part of the main sequence in the Hertzsprung-Russell diagram contains the stars that took the longest to reach the main sequence. These stars are low mass and cool, so they undergo a longer contraction phase before they start fusing hydrogen in their cores and settle onto the main sequence.
What are the main sequence stars also called?
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.
What are the hottest stars in the main sequence also called?
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.
Are main sequence stars called medium sized stars?
No. Main sequence stars are simply stars that are fusing hydrogen into helium and have a specific relationship between color and luminosity. They range from red dwarfs to large O-type main sequence stars.
What do you understand by main sequence stars?
In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
What are the two stars that are not in the main sequence?
There are billions of stars that are not on the main sequence.
What are the stars in the main sequence?
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Main sequence stars are also called stars?
A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime. Our Sun is a yellow dwarf in "main sequence".
Is most stars sequence stars?
"main sequence" is the tern.
What are featureless galaxies that contain old red main-sequence stars and red giants called?
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
What kind of stars are 90 of all Stars?
main sequence stars , our sun is also a main sequence star
Do red main sequence stars have the highest surface temperature?
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
What is the classification of about 90 percent of the stars?
About 90 percent of stars are classified as main sequence stars, which means they are in the stable phase of their lifecycle where they are fusing hydrogen into helium in their cores. These stars follow a pattern on the Hertzsprung-Russell diagram known as the main sequence.
