Is Sirius A a main sequence star?
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions. The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star. Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star. Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star. There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
What stages of a star has the greatest mass?
neutron star
How do stars more massive than four solar masses evolve into neutron stars?
I've seen that figure of 4 times the Sun's mass, but the usual number given is at least 8 times the Sun's mass. Anyway here's the answer: The general idea is that, depending on how much mass is left once the star runs out of fuel, it may become a white dwarf, a neutron star, or a black hole. A star like the Sun goes through a "red giant" star stage then becomes white dwarf star. Stars that are much more massive than the Sun go through a "supergiant" stage. They finally run out of fuel. The core of the star is now mainly iron. If, after running out of fuel, the amount of mass left in the core is more than a certain limit - the Chandrasekhar limit, currently believed to be about 1.39 times the mass of the Sun - the core's "electron degeneracy" pressure is not enough to resist the gravitational force on the core. In this case, the core of the star collapses into a neutron star or black hole and causes a supernova explosion.
What happens star's furnace stops?
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
What is the lifetime for this star in years There is a star elsewhere that has 10 times the mass of the Sun but a luminosity which is 100 thousand times that of the Sun?
If you look at the Spectral classes of stars, you will see that this star is a medium sized Blue-white star(3-18 MSun, 95-52000 LSun, Spectral class B). The average main sequence lifespan of this type of star is, according to the table, is 11-400 million years.
What temperature is bernards star?
3,134 k
If a star begins its evolution with ten times the mass of the sun but ends with two times the mass what object does it form?
It forms a "neutron star".
If a star begins its evolution with 10 times the mass of the sun but ends with 2 times the mass of the sun what type of object does it form?
a neutron star
When the star die what did it become?
During last ages of life of a star, to find what happens in coming ages of life of star. It determines on its mass explained by chandrashekher that if the mass of given star is 2.42 times the mass of our sun then it explodes in the form of supernova. If the mass of given star is less than the 2.42 times the mass of our sun then it shrinks to become white dwarf.
How do you know what star becomes when it dies?
You will know what a star becomes when it dies based off of its mass. If the mass of the star is less than, around, or slightly greater than the sun's mass, it will become a white dwarf. If the mass of the star is a few solar masses, a supernova will happen and a neutron star will be created. If the mass of the star is many times that of the sun, it will explode in a giant supernova called a hypernova and create a black hole.
What happens when a star 3 times 5 times and 20 times the mass of the sun?
Complete Question here: For three mass stars (a) a star with a mass three times the mass of the sun, (b) a star with a mass 5 times mass of the sun and (c) a star with a mass 20 times the mass of the sun --> in each case describe the possible final state of the star after all its fuel is exhausted. --> comment on the masses, size and density of these states. --> for each of the end states, briefly describe experimental observations that allow us to find, identify, and verify the existence of object left after star has exhausted its fuel and collapsed to a final state. As an example how do we know that neuron stars exist.
What is the land mass of Gliese 581?
Not sure what you mean with "land mass". It is a star, therefore it won't have land. Total mass is estimated to be 0.31 times the mass of the Sun (according to information in the Wikipedia).Not sure what you mean with "land mass". It is a star, therefore it won't have land.

What is the mass of Barnards star?
Barnards star has a mass of between 0.15 and 0.17 solar masses.
How many star can form a black hole?
The death of any star greater than about 5 times the mass of our Sun is likely to result in a black hole.
How many times large is a brown dwarf star than Jupiter?
The size should be about the same. The mass, of course, is greater.
What is high mass star?
It's not got an exact definition, but astronomers usually mean a star of about 8 times the mass of the Sun or higher.
Low mass stars will become a when they die. A high mass star will end up as a or a?
A low mass star will become a white dwarf star, eventually this will cool to become a black dwarf. A high mass star (at least 8 times the mass of our Sun) will form a neutron star or a black hole, after a supernova event.
