Question

- Most star systems are....
Single
Binary
Triple

-What is the deciding factor for the how a star will become a main sequence or ginat or super giant? _________

- Which Size star will have the shortest life span and why will it be the shortest? ____________________________

Answer 1

Actually, most stars are binary. Most clusters of three or more stars is a relatively short-lived (cosmologically speaking) association that usually deteriorates to binary systems. When the cluster "sheds" its extra companions, these extra companions will either pair up with another single, if sufficient gravitated to each other, or in less frequent case, remain a single star.

The size of any star is determined by several factors, such as availability and composition of the nebula from which it is formed, any other forces, or field, that may exist in the nebula, etc.

The super giant is usually the shortest-lived star. Its life span has to do with the rate of fusion within the star and that is dependent upon the surface area as opposed to the volume of the star.

RED GIANT STARS because THEY EXHAUST THEIR NUCLEAR FUEL MORE QUICKLY THAN SMALLER STARS

Answer 3

Well, the answer to your first question is that: It depends on how much Hydrogen/Helium (I forget which one is the double of the other) it has clustered together during it's nebula stage.

The answer to your second question is that: the star with the smallest amount of "fuel" (see parentheses above) the star has. If a star has such a small amount that it could only live for a year of so, then it would only live for a year.

Answer 4

1st one is how much mass the star has
the second one is a super giant because it burns itself out the fastest because it uses more of its hydrogen faster
