5. A core-collapse supernova located near the Galactic Center ejects the outer 10 Msun of the envelope of its star star at a speed of 5000 km s1 a. Estimate the kinetic energy of the expanding ejecta b. The remnant core is a neutron star with a mass of 1.6 Msun and a radius of 11 km. Estimate the c. What percentage of the binding energy liberated by the formation of the neutron star was d. Estimate the number of neutrinos emitted during the core bounce (Hint: you get 1 neutrino for e. The IceCube Neutrino Observatory at the South Pole has an effective collecting area of about 1 f. Bonus Points (2): IceCube, as the name suggests, is a cube 1 km on a side, and the cross- gravitational binding energy of this neutron star. You may assume it is uniform density. converted into kinetic energy? reach new neutron made and the pre-bounce core was essentially 100% 56Fe). square kilometer. How many neutrinos from this supernova will pass through IceCube? section for neutrino absorption is ơ~10-48 m2. Estimate how many of the neutrinos in part e would be detected
