What is the difference in the death of your sun and the death of a giant star?

Answer 1

It would enter the post main sequence much faster

______________________________

Big stars "live fast and die young". The more massive the star, the shorter its expected life. Small red dwarf and even smaller brown dwarf stars have a life expectancy that is longer than the current age of the universe (about 14.5 billion years), while very massive stars like Betelgeuse (current age; about 10 million years) may die in a titanic supernova explosion in the relatively near future. ("Relatively soon" to an astronomer means less than 10,000 years.)

One does not normally associate the poems of Edna St. Vincent Millay with the context of astrophysics, but her poem "First Fig" is oddly appropriate in this regard;

My candle burns at both ends; It will not last the night;But ah, my foes, and oh, my friends-- It gives a lovely light!

Answer 2

A very massive star will be much hotter, shine much brighter, and thus use up its fuel much faster. For example, a star that has 10 times the mass of our Sun will produce much more than 10 times the power of our Sun.

Answer 3

In general, no. The bigger the star is, the faster it ages and dies. It's the tiny red dwarf and brown dwarf stars that will outlast the rest of the universe, while big, BIG stars like Betelgeuse are already aged and ready to supernova, after only 100 million years or so.

Our Sun will last about 9 billion years, give or take a few hundred million, and is about halfway through its life. A substantially more massive star will grow old and die in less time.

Answer 4

It is shorter. Even though it has more fuel available, it burns the fuel much faster and ends up with a shorter lifetime.

Answer 5

It will "burn" a lot hotter, have a shorter lifespan and will have a violent death.

Answer 6

a giant star is more likely to go supernova when it dies than a medium size star such as our sun.

Answer 7

The sun will die out in a smaller proportion than a sunlike star, but there is no real difference. both will either create a supernova or die out into a black dwarf... Fudge i love monkeys!!

Answer 8

A low-mass star will live much longer. A high-mass star gets hotter, and uses up its fuel much faster. This cuts its lifetime dramatically.

Answer 9

The difference is our sun will expand and a giant star will collapse on itself
