Ekibin bu hafta yay\u0131mlad\u0131\u011f\u0131 veriler, cismin etraf\u0131ndaki \u0131\u015f\u0131k bulutunun (koma) g\u00fcne\u015ften uzakla\u015ft\u0131\u011f\u0131nda daha h\u0131zl\u0131 b\u00fcy\u00fcd\u00fc\u011f\u00fcn\u00fc, yakla\u015f\u0131rken ise yava\u015flad\u0131\u011f\u0131n\u0131 ortaya koydu. Ara\u015ft\u0131rmac\u0131lar bu de\u011fi\u015fimin, cismin y\u00fczeyinde parlak buz par\u00e7ac\u0131klar\u0131n\u0131n sal\u0131nmas\u0131ndan kaynakland\u0131\u011f\u0131n\u0131 \u00f6ne s\u00fcrd\u00fc.<\/p>\n

Harvard fizik\u00e7isi Avi Loeb, cismin devasa boyutu, a\u015f\u0131r\u0131 parlakl\u0131\u011f\u0131 ve belirgin kuyru\u011funun olmay\u0131\u015f\u0131 gibi nedenlerle 3I\/ATLAS\u2019\u0131n \u201cyapay bir sonda\u201d olabilece\u011fini savunuyor. Ancak Avusturyal\u0131 astronomlar, g\u00f6r\u00fcnt\u00fclerinde koman\u0131n a\u00e7\u0131k\u00e7a g\u00f6r\u00fcld\u00fc\u011f\u00fcn\u00fc vurgulayarak bu iddiay\u0131 reddetti. <\/p>\n

Eyl\u00fcl ba\u015f\u0131nda gaz bak\u0131m\u0131ndan zengin kuyruklu y\u0131ld\u0131zlar\u0131n aktif hale geldi\u011fi e\u015fik a\u015f\u0131ld\u0131. 28 A\u011fustos\u2019ta kuyru\u011fun parlad\u0131\u011f\u0131n\u0131, birka\u00e7 g\u00fcn sonra ise mavi filtreyle al\u0131nan g\u00f6r\u00fcnt\u00fclerde gaz komas\u0131n\u0131n olu\u015fmaya ba\u015flad\u0131\u011f\u0131n\u0131 g\u00f6rd\u00fck\u201d dedi.<\/p>\n

Bilim insan\u0131na g\u00f6re bu, milyarlarca y\u0131l boyunca uzay radyasyonuna maruz kalan cismin y\u00fczeyinde olu\u015fan kal\u0131n kabu\u011fun art\u0131k \u00e7atlamas\u0131yla a\u00e7\u0131klanabilir.<\/p>\n

3I\/ATLAS, ilk y\u0131ld\u0131zlararas\u0131 cisim Oumuamua\u2019dan (gaz ya da toz izi g\u00f6stermemi\u015fti) ve ikinci cisim Borisov\u2019dan (tipik bir kuyruklu y\u0131ld\u0131z gibi davranm\u0131\u015ft\u0131) farkl\u0131 \u00f6zellikler sergiliyor. Anti-kuyruk, a\u015f\u0131r\u0131 renk de\u011fi\u015fimleri ve dev koma bunlar\u0131n ba\u015f\u0131nda geliyor.<\/p>\n

Buna ra\u011fmen Loeb, mevcut verilerden yola \u00e7\u0131karak farkl\u0131 bir tablo \u00e7iziyor. A\u011fustos sonunda \u015eilili astrofizik\u00e7ilerin yay\u0131mlad\u0131\u011f\u0131 \u00e7al\u0131\u015fmaya at\u0131f yapan Loeb, cismin yaln\u0131zca nikel salmas\u0131 ve bunun yan\u0131nda demir bulunmamas\u0131n\u0131n \u201cdo\u011fal olmayan\u201d bir durum oldu\u011funu belirtiyor. <\/p>\n

Do\u011fal kuyruklu y\u0131ld\u0131zlar nikel ve demiri birlikte yayarken, 3I\/ATLAS\u2019\u0131n yaln\u0131zca nikel sa\u00e7mas\u0131 Loeb\u2019e g\u00f6re \u201cend\u00fcstriyel nikel ala\u015f\u0131m\u0131 \u00fcretiminin imzas\u0131\u201d olabilir.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, cismin saniyede yakla\u015f\u0131k 5 gram nikel ve 20 gram siyan\u00fcr sald\u0131\u011f\u0131n\u0131, G\u00fcne\u015f’e yakla\u015ft\u0131k\u00e7a bu miktarlar\u0131n keskin \u015fekilde artt\u0131\u011f\u0131n\u0131 saptad\u0131.
