bee. dee. camelopardalis

bee. dee. camelopardalis ack aiss. taaraa haye aur camelopardalis nakshatr mein sahajeevi taaraa haye. ise 1922 mein ack spectroscopic dwiaadhaari taare key roop mein maanyata dee gaee thee, aur iska kakshiya samadhan 1984 mein prakaashit huaa; isaki 596-divasiya kakshiya avadhi haye. 1986 mein laal vishalkay praathamik taare kaa ack spectroscopic sanrachana vishleshan kiya gayaa thaa.
varnan.
halanki taare kaa varnakram zirconium oxide kii varnakramiya visheshtaon koo darshaata haye joe varnakramiya varg koo paribhaashit kartaa haye, bee. dee. cam apane varnakram mein koee takniki rekha naheen dikhaata haye. aisaa maanaa jaataa haye kii yeh ack "baahya" taaraa haye, jiska aiss-prakriya tatva ack dwiaadhaari saathi taare mein utpann hotaa haye. pranali drishya mein kewal nyuntam bhinnataon koo pradarshit karati haye, lekin saathi kii upasthiti aur drishya laal vishalkay kii taarakiya havaa key saath isaki baatchit parabaingani aur helium kii nikat avarakt varnakramiya rekha mein aasaani seey dekhi jaane vaali samay-parivartansheel varnakramiya visheshtaon koo banaati haye.
kabhi-kabhi bee. dee. cam drishya akash mein sabse chamkila aiss. taaraa hotaa haye, kyonki anya chamkile aiss. taare meera charr yaa anya prakaar key charr taare hotey hain jinamen spasht chamak mein badey parivartan hotey hain. spectrum key drishya bhaag mein isaki apani chamak parivartansheelta mamuli haye.
