Does a low mass star have a longer life then a high mass star?

Answer 1

In order to prevent stars collapsing under their own gravity, some outward pressure must exist. this is supplied by the energy released by nuclear reactions in the core of the star. more massive stars need to burn their nuclear fuel at a much greater rate than smaller stars in order to produce enough energy to balance their much greater gravity. the difference in required reaction rates is actually greater than the difference in mass, consequently the more massive a star is, the faster it expends its fuel.

Answer 2

Yes, low mass stars have longer lifespans than high mass stars. Low mass stars use their fuel more efficiently through nuclear fusion, allowing them to burn for billions of years. High mass stars burn through their fuel at a much faster rate, resulting in shorter lifespans, typically in the millions of years.

Answer 3

More massive stars have much higher temperatures and pressures. Although they have a lot more fuel, it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.

Lower mass stars have lower temperatures, but they have longer lives as they burn their fuel at a much lower rate.

Answer 4

The large a star is the more gravity it has and the hotter it becomes. The hotter the star becomes the faster that it's fuels/gasses will burn, this will cause it to burn out faster than smaller stars which burn more slowly.

Answer 5

Hydrostatic equilibrium occurs when compression, due to gravity, is balanced by a pressure gradient, which creates a force in the opposite direction. A bit like blowing a balloon up, the inward pressure is counteracted by the external pressure of the atmosphere. For stars, this means that the larger the mass of the star, the higher the temperature must be to achieve this balance, and thus they use their supply of hydrogen up more quickly.

Answer 6

Due to their larger mass, they have more gravitation, therefore a larger pressure in the center, and a larger temperature. They spend their fuel much, much faster than a smaller star. Some of them may live a scant few million years, compared to billions of years for stars like our Sun.

Answer 7

Yes because lower mass burns their fuel at a slower time than high mass stars do.

Answer 8

high mass starts burn their fuel much more quickly. and i believe that smaller stars are mroe denser then high mass stars.

Answer 9

Because lower mass stars burn their fuel much more slowly.

Answer 10

No, high-mass stars live shorter, because they get much hotter, and thus use up their fuel faster.
