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.
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.
How many times longer does a 1.5-M star fuse hydrogen in its core than a 15-M star?
A 1.5-M star will fuse hydrogen in its core approximately 7 times longer than a 15-M star because less massive stars burn hydrogen at a slower rate due to their lower core temperatures and pressures. This means they have longer main-sequence lifetimes compared to more massive stars.
