  • Essay / Different Types of Supernovas - 894

    Have you ever wondered what a supernova is? Or even if the word t is a real? Well, I'm going to talk about what a supernova is, what it does, and how it's made. The word supernova is plural for supernovae or supernovae. The definition of a supernova is that any star that violently explodes after a flare suddenly increases several million times its normal level. The supernova was created in the 1930s by Walter Baade and Fritz Zwicky. It is very rare to see supernovas occur every 50 years in the Milky Way. Supernovas cannot be predicted in our galaxies, it is impossible. (“Supernova”)A supernova is the explosion of a massive supergiant star. It can shine with a brightness of 10 billion suns! The total energy output can be 10^44 joules, which is as much as the total output of the sun over its 10 billion year lifespan. The likely scenario is that fusion continues to form an iron core. The "iron group" of elements around mass number A=60 are the most tightly bound nuclei, so more energy can be obtained from nuclear fusion. Supernovas are classified as type one if their light curves show sharp maxima and then gradually disappear. The maxima could be around 10 billion solar luminosities. Type two supernovas have less sharp peaks at maxima and peak at around 1 billion solar luminosities. They disappear more abruptly than type 1. Type two supernovae are not observed in elliptical galaxies and are thought to occur in the population of type 1 stars in the spiral arms of galaxies. Type one supernovas usually occur in elliptical galaxies, so they are likely population type two stars. With the observation of a number of supernovas in other galaxies, a more refined classification of supernovas has been developed based on the observed spectra. The middle of the paper results from short-lived massive stars. They are most often found in Sc-type spirals, but also in the arms of other spiral galaxies and in irregular galaxies, notably star galaxies. ("supernova") Type Ib/c and II-L, and perhaps most Type IIn, supernovae are thought to be produced only from stars with metallicity levels near the Sun that result in massive stars have a high mass loss, so they are less common. in older and more distant galaxies. The table shows the expected ancestor of the main types of core-collapse supernova, as well as the approximate proportions of each in the local neighborhood. ("supernova") Works Cited "Supernova".
