Stars that are more than about three times the mass of the Sun die in a supernova explosion that usually results in a black hole. Stars smaller than that leave behind either a white dwarf or a neutron star.
Since it's impossible (with our current technology) to detect black holes, scientists aren't entirely certain what the precise cutoff between black hole and neutron star is, or whether this is one of those things that could go either way depending on how it happens. We're sure that really large stars leave behind a black hole, and that smaller stars leave a white dwarf. But the in-between parts are a little hazy.
What else can I help you with?
Small dense star that remains after a red giant?
"Stellar masses" is not a unit of mass - perhaps you mean "solar masses". Depending on the remaining mass - after the supernova explosion - either a neutron star or a black hole. In the case of four stellar masses, probably a neutron star; it would require a more massive star than that to become a black hole.
A southern circumpolar constellation that contains the stellar south pole?
The southern circumpolar constellation that contains the stellar south pole is Crux, also known as the Southern Cross. It is a prominent asterism in the southern hemisphere sky and is easily recognizable by its distinctive shape of four bright stars. Due to its proximity to the celestial south pole, Crux remains visible all year round in the southern sky.
What are the four variables astromeners use to classify stars?
The four variables astronomers use to classify stars are temperature, luminosity, size or radius, and mass. By analyzing these properties, astronomers can determine a star's position on the Hertzsprung-Russell diagram and classify it into different spectral types and stages of stellar evolution.
How do the four rocky planets compare to the four gas giants in size?
All four rocky planets are much smaller than gas planets.
Is the Julian calendar eleven days behind the Gregorian calendar?
yesAnswer:The Julian Calendar was 11 days behind the Gregorian Calendar when Britain and its colonies (including the American colonies) finally switched to the Gregorian Calendar in 1752. The difference increases by three days every four centuries. The Julian Calendar is now 13 days behind, and beginning on March 14, 2100 the difference will be 14 days.
What is left behind after a star with four masses has died?
After a star with four solar masses dies, it can collapse and form either a neutron star or a black hole, depending on how much material is left behind after the explosion during its death throes.
What is left after a star with four or more a stellar has died?
A black hole.
Who did Ulysses S. Grant leave behind when he died?
He was survived by his wife , his three sons and his one daughter and three or four grandchildren.
What are the four types of air masses that influence the weather in North America?
The four are Maritime tropical, Continental tropical, maritime polar, and Continental polar
When the masses are doubled and separation is halved what effect do they have on the gravitational force between the masses?
When the masses are doubled and the separation is halved, the gravitational force between the masses increases by a factor of four. This is because the force of gravity is directly proportional to the product of the masses and inversely proportional to the square of the separation distance.
What are the four major types of air masses that influence the weather in North America?
The four are Maritime tropical, Continental tropical, maritime polar, and Continental polar
Does oscillation of universe occur in your universe only or there are more universes?
This is "The theory" which may also explain the acceleration, that is taking place in the universe. Our universe is surrounded by some 4 such universes, probably four pre big bang masses. In turn the four pre big bang masses are surrounded by four universes. Those universes are surrounded again four pre big bang masses. So one universe is surrounded by four pre big bang masses and one pre big bang mass is surrounded by four universes. You can find the structure of carbon atoms in case of diamond to imagine the same. So your universe is getting acceleration due to gravitational forces of the four pre big bang masses and other universes. So there is probably nothing like 'Dark energy", which "Push" the universe. But there are probably four "Pre big bang masses" and other universes, which are "Pulling" your universe from the "Out side" to give acceleration to your universe. It may take another billions of years, for your universe to "Fall", on those pre big bang masses. Once your universe "Fall" on such pre big bang masses, that will initiate "Big bang" there in those pre big bang masses. This theory also explains to why the acceleration in expansion of the universe did not start from the starting of the big bang. The big bang started at the point, where the gravitational force of the outer universes was zero, like Lagrangian points. Once your universe started to expand, it drifted more and more from this zero gravity point. That gave an opportunity to outer pre big bang masses and universes to pull your universe apart, giving it an acceleration.
Where is the lucky four leafed clover on the spring time on fantage?
It Varies.....its not certain and it changes places. I found it at the Lighthouse while my friend found it at Stellar Salon.
Which of the four fundamental forces isn the weakest force?
Gravity is the weakest of the four fundamental forces. Its effects are only noticeable when dealing with large masses such as planets and stars.
What is the religon of Panama?
The major Panama religion, followed by the masses is Roman Catholicism, which is practiced by about four-fifths of the population
What are the four major types of air masses according to moisture content?
Precipitation
