how does a star become a supernova
How does a supernova become a neutron star or a white dwarf? A supernova is more significant than a nova, but less so than a hypernova. A white dwarf with enough mass will eventually go supernova. A supernova, though, happens in only about 15 seconds! When a star goes supernova, its core implodes, and can either become a neutron star or a black hole, depending on mass. What is a Supernova? In Universe Sandbox, a star will become a supernova in the following scenarios: . Supernovae are very bright and generate bursts of radiation that can briefly outshine a whole […] A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs (30 to 1000 light-years) away) to have noticeable effects on Earth's biosphere.. Supernova discoveries are reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams, which sends out a circular with the name it assigns to that supernova.The name is formed from the prefix SN, followed by the year of discovery, suffixed with a one or two-letter designation.The first 26 supernovae of the year are designated with a capital letter from A to Z. Eventually, as the mass increases to about 1.38 times the mass of our Sun, the star erupts in a violent explosion known as a Type I supernova. A supernova is an explosion of a star. You see, a star is a balancing act between two huge forces. This means it will take a very, very long to cool down, billions and billions of years in fact (assuming they act similar to white dwarfs, which behave in this manner for the same reasons I mentioned). As the supply of Helium becomes depleted it starts fusing progressively heavier elements. If the star doesn't have enough gravity to do that, it will release its cooling outer layers into space.) How does a star become a white dwarf? A supernova occurs when a high mass star dies and becomes a neutron star. To say in three words, a supernova is an exploding star. Supernova progenitors – these stars capable of becoming supernovae – are extremely massive, at least 8 to 12 times the mass of our Sun. Type Ib, Type Ic and Type II supernovae stars start out so huge -- possibly 8 times the size of our sun -- that they cannibalize themselves to the point of collapse [source: NASA].A white dwarf eventually created from a star that massive has so much heat and pressure inside its core that lighter elements keep fusing into increasingly heavy elements instead of flying off into space. That increases the mass of the white dwarf. Do you have any links to neutron star cooling curves past 1 million years and below 100 000 K? Supernova - one of the most explosive events known to humankind. When the gas collides with the collapsed core , an explosion begins that races out through the rest of the star , blowing it to pieces . The pieces of the star that are flung off during the shock wave help form new stars. Its evolutionary path depends on its mass. A neutron star is formed during a supernova, an explosion of a star that is at least 8 solar masses. When a star this big runs out of fuel, its core collapses.

A supernova occurs when a star explodes, shooting debris and particles into space. A neutron star must have a minimum mass of at least 1.4x solar masses (that is, 1.4x mass of our Sun) in order to become a neutron star in the first place. How does a star become a supernova or a black hole? The… Asked by: Mudita Upman Answer Stars are sustained by the nuclear fusion reactions taking place in their cores. How does a supernova become a neutron star or a white dwarf? A high-mass star—one with eight or more times the mass of the Sun during the time it's on the main sequence—will explode as a supernova and create a neutron star or black hole. That "star stuff" collects into a disk around the white dwarf, known as an accretion disk. A red giant will lose its outer layers to become a white dwarf. A supernova is the biggest explosion you can imagine, the brilliant, dying gasp of a star that is at least five times more massive than our Sun. See Chandrasekhar limit on wikipedia for details.
