Where a star ends up at the end of its life depends on the mass it was born with. Advanced; Basic; White Dwarfs Where do White Dwarfs Come From? Observationally, how do we distinguish white dwarf and massive star supernovae? As the white dwarf pulls material from a companion star, the temperature increases, eventually triggering a runaway reaction that detonates in a violent supernova that destroys the white dwarf… Supernovae (which is the plural form of supernova) become very bright and cause an enormous burst of radiation that can outshine an entire galaxy before disappearing. When enough gas builts up on the surface of the white dwarf it triggers an explosion. The outburst usually lasts about a month and expels much of a star’s remaining matter at an extremely … The fusion begins almost instantly throughout the star, so the entire star ignites and the white dwarf explodes completely.
A white dwarf supernova occurs when the white dwarf gains enough mass for the carbon interior of the star to begin carbon fusion. A Supernova Explosion in Process. A white dwarf supernova is caused by carbon fusion starting and the carbon fusing all at once causing an explosion A white dwarf supernova happens when an object with little hydrogen collapses while a massive star supernovae has a good amount of hydrogen left in it or its immediate surroundings The fusion begins almost instantly throughout the star, so the entire star ignites and the white dwarf explodes completely. A white dwarf SN is caused by carbon fusion starting, the carbon fuses all at once causing an explosion. A white dwarf SN happens when an object with very little hydrogen in its outer layer collapses so, there is little or no hydrogen absorption in the spectrum. A white dwarf supernova occurs when the white dwarf gains enough mass for the carbon interior of the star to begin carbon fusion. The fusion begins almost instantly throughout the star, so the entire star ignites and the white dwarf explodes completely.
It is a dramatic end to a star’s life. For a brief time, the system can shine up to a million times brighter than normal. A white dwarf supernova occurs when the white dwarf gains enough mass for the carbon interior of the star to begin carbon fusion. Choose the correct description of processes, which cause a white dwarf supernova. A supernova occurs when a super massive star explodes.
Stars that have a lot of mass may end their lives as black holes or neutron stars.A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. A nova occurs when the white dwarf, which is the dense core of a once-normal star, “steals” gas from its nearby companion star.
