The cause of a type ii supernova
網頁2015年10月21日 · Once the core mass of iron exceeds about $1.2M_{\odot}$ (which is the Chandrasekhar mass for an iron composition), then it collapses and we get a type II (core-collapse) supernova. In this route a $3 M_{\odot}$ … 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.

網頁2024年3月31日 · A second type of supernova can happen in systems where two stars orbit one another and at least one of those stars is an Earth-sized white dwarf. A white … 網頁The Type II core collapse of a massive star that produced this supernova remnant ~1600 years ago is located in the direction of the constellation Centaurus. SNR G292.0+1.8 is interesting because it is one of only three oxygen-rich remnants and one of the primary sources of the heavy elements necessary to form planets and people.
網頁Type II supernovas usually occur at the end of a super giant star’s life. They usually result from stars having more than 8 solar masses that are unable to transform into white …

In this "type Ia" supernova, white dwarf's gravity steals material away from a nearby stellar companion. When the white dwarf reaches an estimated 1.4 times the current mass of the Sun, it can … nethergate brewery co limited網頁1987年2月23日 · Type II supernovae are associated with the core collapse of a massive star together with a shock-driven expansion of a luminous shell which leaves behind a rapidly rotating neutron star or, if the core has mass of >2–3 solar masses, a black hole. The typical signal from such an explosion is broadband and peaked at around 1 kHz. it will never lose its power instrumentalA Type II supernova (plural: supernovae or supernovas) results from the rapid collapse and violent explosion of a massive star. A star must have at least eight times, but no more than 40 to 50 times, the mass of the Sun (M☉) to undergo this type of explosion. Type II supernovae are distinguished from … 查看更多內容 Stars far more massive than the sun evolve in complex ways. In the core of the star, hydrogen is fused into helium, releasing thermal energy that heats the star's core and provides outward pressure that supports the … 查看更多內容 The Standard Model of particle physics is a theory which describes three of the four known fundamental interactions between the elementary particles that make up all matter.
