Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?

No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.

How does star color relate to mass?
There is no simple relation. The color does not depend only on the mass. The same star can change color, without a significant change in mass. For example, our Sun is currently yellow; in a few billion years, it is expected to get much larger, becoming a red giant. However, if we limit the sample of stars to those on the "main sequence" of the "HR diagram", there is something of a relation between mass and color. The most massive stars are blue or white. They are also hottest and most luminous. The least massive are the red dwarf stars, which are relatively cool and dim. Our Sun, which is a "main sequence" star at present, is somewhere in between those extremes. (There is a strong relationship between mass and luminosity for main sequence stars. The HR diagram, of course, shows there is a relationship between luminosity and color for the main sequence stars.)
Will a star's lifecycle be shorter or long if its mass is greater?
The way that a star's mass affects it's life span is that when a star is about the same size as our Sun, it's nuclear fusion process occurs much slower and therefore the star lives longer. However, with a high mass star, it's fusion process occurs much faster and therefore a high mass star has a much shorter life span than a low mass star.
Why are most stars you see in the sky main-sequence stars?
most stars you see in the sky are main-sequence stars because stars spend most of there life time as a main secuence stars then they turn into red giants and enggulp the inner planets blow off there outer layer and become white dwarf the will eventually die and give off huge clouds off gas and will become a new star.
When a main sequence star runs out of fuel it becomes a?
Either a giant or a super giant. Giants will eventually collapse on its core and have a little white dwarf left behind, but they will have the same mass and gravity as the old star. Supergiants will collapse but in an explosion, supernova, and they will either become a nuetron star or a black hole.
Which of the following types of star is the most luminous red supergiant red main sequence star white dwarf or yellow main sequence star?
Red Super Giants have already passed their main sequence stage and are on the way to death. Luminosity also depends on how close the star is to us. But for arguments sake we will say that they are all the same distance away. The brightest would be a Yellow Main sequence. Next would be a Red Super Giant, the faintest of all is the white dwarf this is the remaining core of a Red Giant Star, Not Super Giant, that has died. It is very dense, very faint about the size of Earth
What is the difference between a main sequence and a red giant?
A main sequence star is a star that is not surprisingly on "the main sequence". This is the period when a star is fusing hydrogen into helium. Most stars you see in the night sky are main sequence stars.
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
Are the phases for a small star Protstar-Main sequence-Red Gaint- white Dwarf?
Yes, that's correct, for a "low mass" star like our Sun. Smaller stars, with about 8% to 80% of the Sun's mass, are red dwarfs. They follow the same sequence, but without the red giant stage.

How long will a star with a mass the same as your sun stay on the mail sequence?
Around 10 billion years.

Why aren't group 2 and group 3 stars not in the main sequence?
because they are not in the same stellar path as the other bodies

What is the difference between a geometric sequence and arithmetic sequence?
Goemetric sequence : A sequence is a goemetric sequence if an/an-1is the same non-zero number for all natural numbers greater than 1. Arithmetic sequence : A sequence {an} is an arithmetic sequence if an-an-1 is the same number for all natural numbers greater than 1.
How do you get lots of lifetime happiness points in sims 3?
If you press Shift and Ctrl C at the same time in the main menu on the selected family then after that enter "testingcheatsenabled on" then go into the game and go to the lifetime happiness section. then next to the chest click and it will add 500 points to your lifetime happiness! Enjoy!
What is a sequence in which you add the same number to the previous term?
An arithmetic sequence
What is the type of sequence where the terms in the sequence are found by adding the same number each time?
That's an arithmetic sequence.
