lambda urse minoris

lambda urse minoris (λumi, λ urse minoris) ursa minor nakshatr mein ack taaraa haye. yeh ack aim-prakaar kaa laal vishalkay haye jiska spasht parimaan + 6.38 haye aur prithvi seey lagbhag 880 prakaash varsh door haye.
lambda urse minoris ack asymptotic vishal shakha (aeye. jee. bee.) taaraa haye, ack taaraa jisane apane mool hydrogen aur helium koo samaapt curr diyaa haye aur abb apane mool key baahar key koshon mein samagri kaa mishran curr rhaa haye. aeye. jee. bee. taare aksar asthir hotey hain aur spandit honey kii pravritti rakhate hain, aur lambda urse minoris koo ack ardh-rekhiya charr taare key roop mein vargeekrit kiya gayaa haye aur isaki chamak lagbhag 0.1 parimaan seey bhinn hoti haye. isaki parivartansheelta kii khoj hipparcos astrometry seey kii gaee thee aur ise 1999 mein charr sitaaron kii samanya soochi mein darj kiya gayaa thaa.
iss taare kaa upayog 1882 seey 1908 key sanshodhit harvard photometry catalog key liye uttari golardh mein sitaaron key parimaan koo maapane key liye ack sandarbh key roop mein kiya gayaa thaa. sigma octantis kaa upayog dakshini golardh key liye kiya jaataa thaa. taba yeh nott kiya gayaa thaa kii "inmein seey koee bhee taaraa bodhgamya roop seey bhinn naheen prateet hotaa haye" lekin yeh kii, upayog kii jaane vaali prakriyaon key kaaran "yadi way karate hain, tou bhinnata kaa antim upaayon parr koee prabhaav naheen padegaa."
