After a supernova event occurring in a high-mass star, what is left behind?

What is left behind after a supernova event?

Supernova remnant, nebula left behind after a supernova, a spectacular explosion in which a star ejects most of its mass in a violently expanding cloud of debris. At the brightest phase of the explosion, the expanding cloud radiates as much energy in a single day as the Sun has done in the past three million years.

What types of stellar remnants will a high mass star leave behind?

Stars die, and as they do, they leave behind remnants, usually compact objects of some sort, like a white dwarf, or a neutron star. What kind of remnant it is depends on the initial mass of the star, and how it met its’ death.

What happens when a high mass star leaves the main sequence?

Leaving the Main Sequence

High-mass stars become red supergiants, and then evolve to become blue supergiants. It’s fusing helium into carbon and oxygen. … Basically, the star becomes a chemical creation factory, with fusion occurring not just in the core, but in layers surrounding the core.

What is the result of a supernova?

As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova.

What are two objects that can be leftover after a supernova?

The remnants of the stellar core which are left after the supernovae explosion will follow one of two paths: neutron star or black hole.

What two things can happen after a supernova?

The star collapses into a neutron star or a black hole after a supernova explosion.

What stellar remnant will the sun become?

As such, when our Sun runs out of hydrogen fuel, it will expand to become a red giant, puff off its outer layers, and then settle down as a compact white dwarf star, then slowly cooling down for trillions of years.

Which stellar remnant will our sun end up as?

Our Sun will eventually exhaust its core hydrogen and evolve off the main sequence into a red giant.

Why is it easier for a high mass star than a low mass star to burn helium?

Why is it easier for a high-mass star than for a low-mass star to burn helium? … Stars that change in brightness. Time it takes to complete a pulsation cycle.

What happens when all the hydrogen in a star is gone?

Stars Like the Sun

When the core runs out of hydrogen fuel, it will contract under the weight of gravity. … The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.

What is the dominant factor in the life of a star?

To understand the stars, you must understand pressure. From birth to death, the internal pressure of a star created by its own weight is the most dominant factor in the star’s life.

What can we learn about a star from a life track on an HR diagram?

What can we learn about a star from a life track on an H-R diagram? The surface temperature and luminosity the star will have at each stage of its life. When does a protostar become a main-sequence star?

Will we see a supernova?

Supernova Seen From Earth

Life on Earth will be unharmed. But that doesn’t mean it will go unnoticed. … Humans would be able to see the supernova in the daytime sky for roughly a year, he says. And it would be visible at night with the naked eye for several years, as the supernova aftermath dims.

Will our sun go supernova?

Our sun, for example, doesn’t have enough mass to explode as a supernova (though the news for Earth still isn’t good, because once the sun runs out of its nuclear fuel, perhaps in a couple billion years, it will swell into a red giant that will likely vaporize our world, before gradually cooling into a white dwarf).
