Why is accounting for mass loss during giant phases crucial when astronomers model stellar evolution?

Answer

It prevents inaccurate predictions of the star's final white dwarf remnant mass

Failing to incorporate the significant mass loss occurring during the giant phases results in incorrect modeling outcomes, specifically leading to inaccurate predictions regarding the actual mass of the resultant white dwarf remnant.
