The cause of a type ii supernova
網頁We now believe we have found the solution to this problem: type Ia supernovae occur when two white dwarfs directly collide with each other. The explosion is triggered by the shock waves that result from the collision, which occurs at velocities of thousands of kilometers per second due to the gravitational pull of the white dwarfs. 網頁2024年11月12日 · Type II supernovae occur when a large star runs out of fuel, which brings it into a rapid collapse and explosion. Such a star is between eight and 40 times heavier than our sun. They are...

網頁2001年1月21日 · In this paper we argue that there is strong observational evidence that the merger of two CO white dwarfs produces both a supernova explosion and a stellar remnant; and further, that since such a supernova does not involve hydrogen it must be of Type I, and probably of Type Ia.

The star's structure is supported against gravity by the heat being generated in its core by fusion processes. When the star burns all the fuel in its core to iron, fusion stops (the heat source is extinguished) and gravity then takes over and collapses the star. taif clinic網頁Figure 21.7 The light curves of typical Type I and Type II supernovae. In both cases the maximum brightness or intensity can reach nearly 10 billion Suns, but there are characteristic differences in the falloff of the luminosity after the initial peak.
