R\u00f5ngastega taevakehi tundub P\u00e4ikeses\u00fcsteemi juurde tulevat. Astronoomid on m\u00e4rganud, et kentaur Chironi suhteliselt hiljuti avastatud r\u00f5ngastik on alles verinoor ja veel kujunemisj\u00e4rgus.<\/p>\n

Rahvusvaheline teadlasr\u00fchm eesotsas Chrystian Pereiraga Brasiilia Rahvusobservatooriumist kirjutab ajakirjas The Astrophysical Journal Letters<\/a>, et Chironi ja ta l\u00e4hinaabruse viimatisel vaatlusel saadud andmetes on ilmnenud selgeid erinevusi varasemail vaatlusil n\u00e4htuga, mis viitavadki kiirelt arenevale r\u00f5ngastikule.<\/p>\n

<\/p>\n

Chiron on Saturni ja Uraani orbiidi vahel \u00fcmber P\u00e4ikese tiirutav, alla 200 kilomeetrise l\u00e4bim\u00f5\u00f5duga keha: avastatud aastal 1977, peetud nii asteroidiks, komeediks, v\u00e4ikeplaneediks kui ka t\u00e4iesti uue taevakehade klassi, kentauride esimeseks avastatud esindajaks.<\/p>\n

Aastal 2011, kui Chiron \u00fche t\u00e4he eest l\u00e4bi liikus, m\u00e4rgati ta \u00fcmber kergeid vihjeid r\u00f5ngaste v\u00f5imalikkusele.<\/p>\n

Hilisematel varjutustel on r\u00f5ngaste olemasolu saanud kinnitust, kuni n\u00fc\u00fcd on Pereira ja kolleegid tunamulluse vaatluse p\u00f5hjal tulnud v\u00e4lja v\u00e4itega alles tekkivast s\u00fcsteemist.<\/p>\n

Sellest, kuidas Chironi r\u00f5ngad t\u00e4hevalgust ajutiselt tuhmistasid, j\u00e4reldasid teadlased, et kolm kindlapiirilist ja tihedast materjalist r\u00f5ngast on olnud esimesest vaatlusest peale enam-v\u00e4hem \u00fchesugused.<\/p>\n

Kuid v\u00e4rskeimas vaatluses s\u00e4ttis end pildile uus kettalaadne moodustis, mis laiub Chironist 200 kuni 800 kilomeetri kaugusel, on seega varem tuttavatest r\u00f5ngastest m\u00e4rksa laiem, aga ka h\u00f5redam.<\/p>\n

Teadlased arvavad, et uus ketas v\u00f5is tekkida m\u00f5ne v\u00e4iksema taevakeha kokkup\u00f5rkel Chironiga v\u00f5i aine eraldumisel Chironist mingil sisemisel p\u00f5hjusel.<\/p>\n

Veel m\u00e4rkasid Pereira ja ta kaaslased, et ka Chironist p\u00e4ris eemal, umbes 1400 kilomeetri kaugusel paistab leiduvat veel \u00fcks suhteliselt h\u00f5redast ainest moodustis.<\/p>\n

Et p\u00e4ris kindel olla, kas Chironi r\u00f5ngad on t\u00f5epoolest alles tekkej\u00e4rgus v\u00f5i ainult n\u00e4ib see praegu nii, tuleb neid vaadelda veel edaspidiste t\u00e4hevarjutuste ajal.<\/p>\n

Huvitavam oleks kahtlemata tekkej\u00e4rgus olek, sest see v\u00f5imaldaks astronoomidel saada uut p\u00f5nevat infot kosmiliste arengute kohta reaalajas.<\/p>\n

Pildil on Chiron ja ta r\u00f5ngad kunstniku kujutuses.<\/p>\n
