> The Star's mass remains the same What makes you think so? I'm no expert, but matter is definitely expelled in the process of forming a white dwarf. The stuff scouring the inner planets doesn't appear out of thin air... This random paper also appears to say that the mass lost is on the order of half the initial mass: https://iopscience.iop.org/article/10.3847/1538-4357/aadfd6/pdf https://iopscience.iop.org/article/10.3847/1538-4357/aadfd6/... > total stellar mass loss ranges from 33% of M_initial at 0.83 M_sun to 83% of M_initial at 7.5 M_sun.
