it depends on the star. size can determine "lifespan", and other conditions as well.
About the same as our Sun. About 10 billion years.

The life expectancy of a star (E) depends on its mass (M), roughly following the model of E = M-2.5. For a star with a mass twice that of our sun (enter 2 in place of `M`), then the lifespan will give 0.177. Our suns lifespan is around 10 billion years, so this would equate to 1.77 billion years.
The average lifespan of a star like Spica is around 10 million years.
Our sun is just about in the middle of its lifespan. It will die in roughly 5 billion years.
