•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
