Textbooks say: Sun ends as white dwarf after ejecting planetary nebula (PN) Our calculations show mass loss on AGB is relatively low (0.116 Msun) because most of envelope lost on RGB PN usually emitted by superwind as part of last thermal pulse on AGB – but our calculations show only 0.0075 Msun is lost in final pulse – much less than a normal PN mass. So any PN would be very tenuous and faint A final thermal pulse after leaving the AGB causes final mass loss, and the expected final WD mass is 0.5405 Msun.
