What else can I help you with?
Is it true that when a nova destroys the star and leave behind a white dwarf?
Yes, when a star undergoes a nova, it expels material into space, which can eventually form a white dwarf. A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and collapsed under gravity. Novae are different from supernovae, which are more energetic and can leave behind other remnants like neutron stars or black holes.
Can the sun leave a black hole when it dies?
No. It is not nearly massive enough. When the sun dies it will leave behind a remnant called a white dwarf.
Will the sun become a supernova or black hole?
No. When the sun dies it will expel its outer layers in a series of gradual pulses and leave behind a white dwarf.
What remains after a low-mass or medium-mass star dies?
After a low-mass or medium-mass star dies, it will typically leave behind a remnant called a white dwarf. A white dwarf is a dense, Earth-sized core made primarily of carbon and oxygen. It gradually cools and fades over billions of years.
Is a dead star the some as a black dwarf?
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
What causes a white dwarf supernova?
A white dwarf supernova occurs when a white dwarf star in a binary system accretes material from a companion star, causing it to exceed the Chandrasekhar limit (1.4 solar masses). The core then undergoes a runaway nuclear fusion reaction, leading to a catastrophic explosion that destroys the white dwarf.
What type of stellar corpse will the Sun leave behind?
The Sun will leave behind a white dwarf as its final stellar corpse. After exhausting its nuclear fuel, it will shed its outer layers, creating a planetary nebula, while the remaining core will cool and shrink to form the white dwarf. This dense, Earth-sized remnant will eventually fade away over billions of years, ultimately becoming a cold, dark object known as a black dwarf, though the universe is not old enough for any black dwarfs to exist yet.
An average star wiill eventually becomes a?
An average star like our sun will eventually become a red giant as it exhausts its nuclear fuel. After that, it will shed its outer layers to form a planetary nebula and leave behind a dense core called a white dwarf.
Is a white dwarf capable of fusing elements?
Not normally. A white dwarf is the remnant of a star in which fusion has stopped. If, however, a white dwarf has a close binary companion star it can accrete gas from that companion. If enough gas collects on the white dwarf it can ignite a complex reaction change between the hydrogen gas and the carbon, nitrogen, and oxygen of the surface. Unlike the steady fusion in a main sequence star, the fusion on a white dwarf is a runaway reaction that results in a massive explosion called a nova, which drives away the accreted gas and ends fusion. If the white dwarf is massive enough the accretion of gas can trigger carbon fusion inside the white dwarf, resulting in an even larger explosion called a type Ia supernova, which destroys the white dwarf.
Will a yellow star eventually become a white dwarf?
Generally yes, however in some rare cases such as yellow supergiants, they will explode as a supernova and leave behind, either a black hole or a neutron star.
What is the name of the white trails that jets leave behind?
The white trails left behind jets are known as contrails.
What is the term for the very dense white dwarf star that is left behind after a supernova?
Neutron Star
