Have you ever wondered what a supernova is? Or even if the word t is a real? Well I’ll be talking about what a supernova is, what it does, and how it is made. The word supernova is plural for supernovae or supernovas. The definition of a supernova is any violently exploding stars after eruption suddenly increases many millions of times its normal level. The supernova came around the 1930’s by Walter Baade and Fritz Zwicky. Supernovas are very rare to see they happen every 50 years in the Milky Way. Supernovas cannot be predicted in our galaxies it is impossible.(“Supernova”) A supernova is an explosion of a massive supergiant star. It may shine with a brightness of 10 billion suns! The total energy output may be 10^44 joules, as much as …show more content…
They are classified as IB if they strong helium lines, and IC if they do not. Type two supernovas have strongly hydrogen lines. These spectral have special features.(“supernovae”) Current models we have of supernovas are The type codes described above that astronomers give to supernovae are taxonomic in nature: the type number describes the light observed from the supernova, not necessarily its cause. For example, type Ia supernovae are produced by runaway fusion ignited on degenerate white dwarf progenitors while the spectrally similar type Ib/c are produced from massive Wolf-Rayet progenitors by core collapse. The following summarizes what astronomers currently believe are the most plausible explanations for supernovae. (“Supernova”) Supernovas are classified as type one if their light curves exhibit sharp maxima and then die away smoothly and gradually. The model for the initiation of type one supernova is the detonation of the white dwarf when it collapses under the pressure of electron degeneracy. It is assumed that the white dwarf accretes enough mass to exceed the Chandrasekhar limit of 1.4 solar masses for white dwarf. The fact that the spectra of Type one supernova are hydrogen poor in consistent with this model since the white dwarf has almost of the energy output would be from the radioactive delay of the unstable heavy elements produced in the explosion. Type two supernovas are modeled as implosion
