Could our sun ever undergo a nova or a white dwarf supernova event explain?

Could our sun ever undergo a nova or a white dwarf supernova event explain?

1) Could our Sun ever undergo a nova or a white-dwarf supernova event? Why or why not? Answer: No, because both events occur on white dwarfs in close binary systems. Even after our Sun becomes a white dwarf, such events won’t occur because our Sun is not part of a close binary.

Can our sun ever become a supernova?

The Sun as a red giant will then… go supernova? Actually, no—it doesn’t have enough mass to explode. Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now.

Will our Sun eventually become a nova?

Our Sun will eventually become a nova. Our Sun will never become hot enough for carbon nuclei to fuse. The nova event is created by the helium flash. Our Sun will likely die as a Type I supernova in about five billion years.

Could the sun become a white dwarf supernova quizlet?

D) The white dwarf gains enough mass to exceed the 1.4-solar-mass limit. Will our Sun ever undergo a white dwarf supernova explosion? Why or why not? A) No, because it is not orbited by another star. B)

Why won’t our Sun become a supernova?

The Sun would need to be about 20 times more massive to end its life as a black hole. Some smaller stars are big enough to go supernova, but too small to become black holes — they’ll collapse into super-dense structures called neutron stars after exploding as a supernova.

Why won’t the Sun become a supernova?

The sun is significantly too small to go supernova. A star needs to be at least 8 solar masses, and perhaps as much as 15. Our sun will swell into a red giant, and then collapse back to a white dwarf.

What would happen if our Sun went supernova?

If the Sun went supernova it would have a much more dramatic effect. We would have no ozone. With no ozone, skin-cancer cases would skyrocket. All living things would suffer from severe radiation burns, unless they were underground or in protective suits.

What if our Sun went supernova?

What would happen if the Sun become a white dwarf?

With its thermonuclear fuel gone, the sun will no longer be able to shine. The immensely high pressures and temperatures in its interior will slacken. The sun will shrink down to become a dying ember of a star, known as a white dwarf, only a little larger than Earth.

What happens when our sun becomes a white dwarf?

Stars that are comparable in mass to our Sun will become white dwarfs within 75,000 years of blowing off their envelopes. Eventually they, like our Sun, will cool down, radiating heat into space and fading into black lumps of carbon.

What is the reason why there is an upper mass limit for white dwarfs quizlet?

B) The more massive the white dwarf, the greater the degeneracy pressure and the faster the speeds of its electrons. Near 1.4 solar masses, the speeds of the electrons approach the speed of light, so more mass cannot be added without breaking the degeneracy pressure.

Will our sun go nova or supernova?

Our sun is too small to go nova or supernova. It will ultimately enter a red giant stage and then collapse as a white dwarf. It would need to be at least eight times more massive to nova.

Can the Sun explode as a white dwarf supernova?

For the sun to be involved in a white dwarf supernova explosion it would need to have a close binary companion which it doesn’t have. A white dwarf needs a close red giant companion from which it can acquire sufficient material to collapse and to explode as a supernova.

Will the Sun ever fuse carbon into iron?

A) No, because it is not orbited by another star. B) Yes, when it becomes a white dwarf. C) No, because the Sun’s core will never be hot enough to fuse carbon and other heavier elements into iron. D) Yes, right at the end of its double-shell burning stage of life.

What happens when a neutron star becomes a black hole?

A) If enough mass is accreted by a neutron star, it will undergo a supernova explosion and leave behind a black-hole remnant. B) During a supernova, if the mass of the infalling core has enough gravity to overcome neutron degeneracy pressure, the core will collapse to a black hole.
