When a stellar iron core collapses, large numbers of neutrinos are formed, and then:
A)they form the neutron star.
B)they are absorbed by electrons to produce positrons.
C)they are captured to form heavy elements.
D)they are captured to form light elements.
E)they immediately pass through the core and escape to space.

Question

Quizplus · Accepted Answer

Neutrinos produced during a stellar iron core collapse are extremely high energy and interact very weakly with matter. This means that they can pass through the core and escape to space without being absorbed or captured by any other element. The large numbers of neutrinos formed when a stellar iron core collapses immediately pass through the core and escape to space.
