Spica is a dual star system, with the two members too close for resolution by the best telescopes. The larger, primary star is a blue-white giant, and does have the potential to end it's life as a supernova. The primary is not a main sequence star. The secondary, about 70% the size of the primary, is a main sequence star, also blue white.

What is the number of years a star stays in main sequence?
The length of time that a star stays in the main sequence varies by a huge amount depending on its mass. The whole reason is much too long and complicated to be placed here. (You need to read an encyclopedia article on the different classes of the starts.) However, the simple summary is that the largest (and hottest) stars stay in the main sequence for the shorter lengths of time (like 10 million years), but the smaller and cooler stars (smaller than our Sun) stay in the main sequence for the longest lengths of time - billions and billions of years, really long, like 50 billion years. Our Sun is in between, and it has an estimated lifetime of about five billion years on the main sequence.
How do large mass star stay in the main sequence?
The "main sequence" basically consists of all those stars that fuse hydrogen-1, converting it into helium-4. A massive star will remain in the main sequence while it has enough hydrogen-1; but since it gets hotter and burns its fuel much faster, it may stay there only for a fairly short time - in the case of the most massive stars, just a few million years.
Why is there an upper mass limit for main-sequence stars of about 100 solar masses?
Objects above this mass fuse hydrogen too rapidly and cannot stay together.

What stage is the star Capella in right now?
Capella is in fact a quad star system, and not one star.One binary pair are still on the main sequence and close to becoming red giants.The other binary pair, are red dwarfs and will stay that way for trillions of years.
The main squence lifetime of an O star compared with an M star?
An O star will stay on the main sequence for millions of years whereas a M star can stay on the main sequence for billions and billions of years.
The Sun will stay on the main sequence for?
About another 4.5 to 5 billion years

How long will a star with a mass the same as your sun stay on the mail sequence?
Around 10 billion years.
What is the primary source of energy for a sylphlike star after it has entered the main sequence and for how long will it typically stay there?
The energy source is hydrogen undergoing nuclear fusion to helium. The time that lasts depends on the mass of the star but it usually takes a few billion years.
When does a protostar becomes a main sequence star?
As the gases in a protostar begin to collapse, the central core begins to heat up due to pressure. As more gases are absorbed, the greater the pressure. Once the temperature of the core reaches 10 million degrees K, hydrogen fusion begins, and the star begins it's life on the main sequence. The star will stay on the main sequence whilst it still has hydrogen to fuse. Once all the hydrogen has been used, the star will drop out of the main sequence. Protostar stage in the stellar evolution. [See related question]
Why is there an upper mass limit for main-sequence stars of about 100 solar masses?
Objects above this mass fuse hydrogen too rapidly and cannot stay together.
Why there are so many Main Sequence stars compared to the much smaller percentage of stars that are Red Giants and White Dwarfs?
For three reasons. 1) Hydrogen is the most abundant element in the universe. 2) ALL stars spend a part of their life on the main sequence because wile on the main sequence the fuel they are fusing is Hydrogen. 3) For a given mass of hydrogen, the energy output created by fusing hydrogen is the greatest of all fusible elements (i.e the elements up to Iron). Thus as stars start fusing other elements (and thereby moving off the main sequence) they burn through their fuel very quickly and either explode a supernovae or decay into white dwarfs (depending on their initial mass). One may also note that the most common type of stars are red dwarf stars on the main sequence and this is because the rate of hydrogen fusion depends on the stars mass a really big star will only last a few million years while a small red dwarf will shine for trillions of years. Thus the big stars die quickly while the small ones last a long time so one ends up with more of them (more smaller stars may also be produced in the first place too).
Does the blue main-sequence star have a longer life than other stars?
It depends on the mass of the star. The lower the mass, the longer it will stay on the main sequence. A red dwarf may stay on the main sequence for trillions of years, while a blue star only lasts a few million years.
