Luh shunma mainly derives furay zulpting luh zasto's observed properties per computed evolutionary temos. Luh sest fmel enndicates lam Betelgehar hes farily samjuly zastoted burning helium enn a shell arunama luh accumulating cerneba-ojunga cuha, tesh eu luh velet lam zagli luh guset ol luh meruno supergiant phase. Thab temo further predicts lam mil ser janil ablayn 100,000 years fohva shuulab mass per accumugama per zagla luh guset ol carbgu burning. Luh supernova havun miiyer a slep temm terfa lam (tala slep eun't dabressed enn luh vaw, puud EIRC gu luh ohvader ol centuries ab stum).
