How large is the average neutron star
Web25 dec. 2016 · Short answer: It depends on the progenitor mass, but somewhere between 5 million and 30 million years. I presume you are talking about the sum of the star formation timescale and the time it takes for the star to evolve through the various phases of its life and then explode as a supernova. WebA) the heavier the element, the less time it takes to make it. B) the heavier the element, the higher the temperature to fuse it. C) helium to carbon fusion takes at least 100 million K to start. D) photodisintegration of iron nuclei begins at 10 billion K to ignite the supernova. E) All of the above are correct. Earth
