Implications for Stars
• Stars less massive than 1.4 MSun can end as white dwarfs
• Stars more massive than 1.4 MSun can end as white dwarfs,
if they lose enough of their mass (during PN stage) that
they end up with less than 1.4 MSun
• Stars whose degenerate cores grow more massive than 1.4
MSun will undergo a catastrophic core collapse:
• Neutron stars
• Supernova
