What else can I help you with?
Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
Is white dwarf a massive star?
No. A white dwarf is the remnant of a low to medium mass star.
Is sirius a medium star?
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
Is Sirius a medium mass star?
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
What are the last two elements that a massive star produces?
The last two elements produced by a massive star before it undergoes a supernova are iron and nickel. During the star's life cycle, nuclear fusion progresses to heavier elements, but iron is the most stable and does not yield energy through fusion. Once iron accumulates in the core, the star can no longer generate the necessary pressure to counteract gravity, leading to its collapse and subsequent explosion.
How long does the main phase last in a massive star?
The more massive the shorter - down to just millions of years.
What is the life span of a star?
It varies considerably. A star similar to our sun will last about 10 billion years. The least massive stars may last trillions of years wile the most massive may last only a few million.
How long would main sequence star last if twice as massive as the sun?
A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
Which star lives longer smaller or bigger?
Smaller stars last longer.
Is the sun a massive star or a dwarf star?
its not a massive or a dwarf star
What is a massive collapsed star?
A massive collapsed star is a dead star.
What do medium stars in the red giant phase become?
A star that is in it's teenage years(medium star) isn't a red giant until it's last years.
