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.
The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
What stars are the oldest red dwarfs white dwarfs red stars or giant stars?
The oldest stars are typically red dwarfs, which are small, cool, and faint stars that have long lifespans. White dwarfs are the remnant cores of low to medium mass stars, not the oldest. Giant stars are intermediate stage stars that have evolved away from the main sequence.
Why are there no white dwarfs among the 100 brightest stars?
White dwarfs have very small surface areas compared to main sequence stars and therefore cannot emit as much light.
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
Giants supergiants white dwarfs have left the main sequence?
Yes, all those types of stars have left 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.
Do stars die out after becoming white dwarfs?
No. Stars become white dwarfs after dying.
Where on the Main Sequence are stars cool and dim?
None of them are cool and dim; the one in the white/black dwarfs are cool and dim.
Are the brightest stars white dwarfs?
No. White dwarfs are fairly dim. The brightest known stars are generally Wolf-Rayet stars.
Name the four main types of stars?
The four types of stars are; Main Sequence, White Swarfs, Red Giants and Super Giants. 90% of stars are in the Main Sequence.
Do all stars begin as white dwarfs?
No. Stars do not start as whit dwarfs. A white dwarf is the remnant of dead star.
