Although it is true that neutron stars have, for the most part, consumed all their internal thermonuclear fuel, they tap into other energy sources to produce light. Indeed, neutron stars are remarkably "resourceful" and employ a variety of physical mechanisms to make themselves visible.A newborn neutron star is incredibly hot ? ... Atlas of the Stars . ...
