It's the size. A dwarf star has reached the end of the road and has collapsed. It's a little old star and people don't notice it, mostly.

Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
The star Algol is estimated to have approximately the same luminosity as the star Aldebaran and approximately the same surface temperature as the star Rigel Algol is best classified as a?
Algol is a blue main-sequence star in the constellation Perseus
Where is Hamal on the main sequence?
Unfortunately, it is impossible to tell accurately where a star is on the main sequence.
Is Sirius A a main sequence star?
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions. The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star. Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star. Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star. There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
How do you explain what the differences are between main sequence stars white dwarf stars and supergiant stars?
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
How does a neutron star differ from a main sequence star?
A neutron star is a stellar remnant
What celectial body is the most common star in the main sequence?
There are more red dwarfs than any other type of star.
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}
How far is the main sequence star from sun?
Do You Know That The Sun Is How Far From Main Sequence Or Called White Dwarfs .. The Sun Is Our Star And It's Size Is Medium-Sized The Far As 8,400 Solar Radii In Sun ,,
What type of star is less bright than the sun?
On the main sequence, red dwarfs and orange dwarfs are less bright than the sun. Our sun is a yellow dwarf.
What is the name for older stars?
"Main sequence" stars are no longer new, and are just cookin' along for millions of years. "Main sequence" stars, depending on their weight and whether they orbit another nearby star can get old and become red dwarfs, white dwarfs, black dwarfs, neutron stars, novas, or super-novas.
When does a star lose its main sequence?
Stars don't "lose" their "main sequence", because it's not something a star can "have" in the first place.Stars are more properly described as being "on" or "off" the "main sequence", and "sequence" isn't a good word for it anyway, because it implies that there is an actual sequence of events involved; in fact, the normal life sequence of a star has it going off the main "sequence".It may help if you stop thinking of them as "main sequence" stars and start thinking of them as either dwarfs or type III stars.
Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
What type of star is most likely to be found on the main sequence?
The curve that contains most stars is called the "Main sequence". The stars on that curve are known as "main sequence stars". Their main characteristic is that they get their energy from fusing hydrogen-1 into helium-4.
How differ the sun and polaris?
The sun is a main sequence star whereas Polaris is a super-giant.
Do dwarf stars emit light?
Brown Dwarfs (maybe not true stars)Red Dwarfs (on the main sequence)Orange Dwarf (on the main sequence)Yellow Dwarfs (stars smaller than our sun but on the main sequence)White Dwarfs (old stars that have run out of hydrogen and are now off the main sequence)Neutron Stars (old large stars who's cores have collapsed during a supernova)---------------------------------------------------------------------------------Red dwarf - Like Proxima Centauri.White dwarf - A degenerate star. The remains of a Sun like star.Yellow dwarf - A G type main sequence star, like our own SunBlue dwarf - A hypothetical star formed from a red dwarf.Brown dwarf - A star that did not have enough mass to initiate nuclear fusion.Black dwarf - A hypothetical star formed when a white dwarf has cooled to absolute zero.Orange dwarf. A K type main sequence star, like Alpha Centauri B
What does the prostar do?
A prostar is sometimes refered to as a young star. It is a star early in its formation created in a nebula. What a prostar will do is develop into a star you know, such as main-sequence stars, supergiants, or dwarfs. It all depends on the mass of the star on what it will form into.
