Stars more than 10 times the mass of the Sun through their short lives fuse hydrogen to helium, helium to carbon, then heavier and heavier elements until their cores are made mostly of Iron, the most tightly packed atomic nucleus.

Nobel prizes and more came over the following years and decades, some with controversy. In this AstroChat we will discuss stars with twice the mass of the Sun, but only 20 km in diameter, with densities of billions of tons per cubic centimetre, spinning insanely quickly – some faster…
