What else can I help you with?
Main sequence lifetime is determined by what?
The mass of the star. The bigger it is, the faster it will burn through its fuel supply.
Will the sun burn out in your lifetime?
It will burn out eventually, but that will be very far from now, not in our lifetime.
Is the lifetime of a massive star shorter or longer than a star like the sunwhy?
The lifetime of a massive star is shorter than that of a star like the sun. Massive stars have more fuel to burn but burn it at a faster rate due to their higher core temperatures and luminosities. This leads to a shorter lifespan for massive stars compared to sun-like stars.
The lifetime of a star depends on its?
The life of a star depends on the amount of hydrogen a star has left. Simple answer the larger the star the shorter the life span for example: stars like our Sun can be expected to live 8-12 billion years a more massive star like Beetlegeuse can expect to live 100-400 million years and the most massive stars like S. Doradus and VY Canis Majoris can expect to live just a few million years. The larger the star the more fuel it consumes. Due to contrary belief not all stars burn hydrogen some stars burn helium others burn carbon some even burn oxygen this is all based off the core temperature the hotter the core the more elements it can burn
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
How the lifetime of stars depend on their mass?
The lifetime of a star is determined by its mass because more massive stars burn through their fuel faster due to higher core temperatures and pressures. Higher-mass stars undergo fusion at a quicker rate, leading to a shorter lifespan compared to lower-mass stars. Conversely, lower-mass stars burn their fuel more slowly, allowing them to exist for billions of years.
When will the sun cease to be as you know it?
Nothing that you will notice in your lifetime . In millions of years, the sun , being a star will first expand , burning up the earth and then reduce and burn out.
How is the lifetime of a star comparable to stellar evolution?
Stellar evolution is the term for the changes a star undergoes during its lifetime.
What is the difference between burn time and bulb lifetime in flashlights?
Burn time is time from power on to power off, but the lifetime is time from the first using to not available.
Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Which star has a shorter lifetime on the main sequence a blue O star or a yellow G star?
an o-type blue star has a less length life than a g-type sun like star, this is because a the larger, hotter star, (the o-type blue star) uses its fuel (converting hydrogen into oxygen) quicker, so the correct answer to your question is the o-type blue star.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
