  • Type II supernova - Wikipedia
    A Type II supernova or SNII[1] (plural: supernovae) 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 [2]
  • What is A Type II Supernovae - Super Giant Star Stellar Explosion
    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 dwarfs At the end a star’s life, the fuels become exhausted and nuclear reactions ensues
  • The different types of supernovae - Astronomy Magazine
    Emerging from theories dating back to 1980, electron-capture supernovae, sometimes classified as Type III supernovae, are reserved for stars of 8 to 10 solar masses
  • Type II supernova | astronomy | Britannica
    In supernova: Type II supernovae The so-called classic explosion, associated with Type II supernovae, has as progenitor a very massive star (a Population I star) of at least eight solar masses that is at the end of its active lifetime (These are seen only in spiral galaxies,… Read More; cosmic rays In cosmic ray: Origin of cosmic rays
  • Type II Supernovae - astro. sunysb. edu
    • The luminosity at peak of a Type II supernova is about 1043 erg s • It is brightest for about a month and therefore radiates about 1049 erg • The outer several solar masses of the star are ejected at velocities up to 1% the speed of light • The kinetic energy of the ejected mass is about 1051 erg
  • The Evolution of Massive Stars and Type II Supernovae
    A large quantity of neutrinos get created in reactions in the core, and the rebounding core and the newly created neutrinos go flying outward, expelling the outer layers of the star in a gigantic explosion called a supernova (to be precise, a type II or core collapse supernova)
  • Supernovae - HyperPhysics
    Type II supernovae have less sharp peaks at maxima and peak at about 1 billion solar luminosities They die away more sharply than the Type I Type II supernovae are not observed to occur in elliptical galaxies, and are thought to occur in Population I type stars in the spiral arms of galaxies
  • Type II Supernovae
    There are several scenarios that can result in a supernova event; however, supernovas are classified by the type of triggering mechanism that initiates the destruction Type II supernovas are produced by the core collapse of a massive star – RCW 86 and SN 1987A mentioned above are Type II events
  • Imagine the Universe!
    For a Type Ia supernova, the energy comes from the runaway fusion of carbon and oxygen in the core of a white dwarf Where does the core go? When the core is less massive than about 5 solar masses, the neutrons are successful in halting the collapse of the star creating a neutron star
  • Type II Supernova | COSMOS - Swinburne
    Recognised as a distinct type of supernova in the early 1940s, Type II (SNII) are characterised by hydrogen emission in their spectra, and light curve shapes that differ significantly from those of Type I supernovae
