Step-by-Step Solution:
Step 1 of 3

Chapter 18: The Bizarre Stellar Graveyard  White Dwarfs o What is a white dwarf  A white dwarf is the core of a low or intermediate mass star after it runs out of fuel, and fusion stops. It begins hot and colds slowly over time.  Electron degeneracy pressure keeps White dwarfs from collapsing  No white dwarf has reached the “black dwarf” coolness.  White dwarfs are high density, the more mass, the smaller it is.  Mass of the sun, but the size of the earth  White dwarfs cannot be bigger than 1.4M sun o What can happen to a white dwarf in a close binary system  Mass exchange happens when two stars are close the each other. \  One star dumps mass on the other  Mass falling toward a white dwarf has some angular momentum and this matter orbits the white dwarf in an accretion disk  Friction causes the accretion disk to heat up, and matter falls on the surface of the star  The temperate of the surface becomes hot enough for hydrogen fusion. Fusion begins suddenly and causes a nova.  Nova star system becomes much brighter and causes an explosion that drives the accreted matter out into space.  Two types of Supern
