An estimate for the maximum mass of a white dwarf is given by: 2 MWD = (-) × (27) ¹/² × (he) ³/2 × ² × (he) ³/² × (Y) ² X 128 where my is the mass of a hydrogen nucleus and Ye is the number of electrons per nucleon. When the dominant isotope of helium is helium-4, this maximum mass of a white dwarf is 1.1 Mo. If the dominant isotope of helium were ³He instead of 'He, calculate what the maximum mass for a helium white dwarf would be. In terms of stellar structure, explain how the change in the dominant isotope of helium leads to a change the maximum mass.
