Keset meie armsat Linnutee-galaktikat laiub hirmus suur must auk. Selle nimi on Sagittarius A* ja enam-v\u00e4hem sellesuguseid leidub teistegi galaktikate keskmes.<\/p>\n

Rahvusvaheline teadlasr\u00fchm eesotsas Florian Pei\u00dfkeriga Saksamaalt K\u00f6lni \u00dclikoolist on n\u00fc\u00fcd avastanud, et Sagittarius A* \u00fcmber tiirutab hulk taevakehi ja nende s\u00fcsteeme t\u00e4iesti stabiilsetel orbiitidel.<\/p>\n

Sellise v\u00f5imsa koletise nagu Sagittarius A* l\u00e4hedal, mis rebib oma ilmatu tugeva raskusj\u00f5uga endasse k\u00f5ik, mis saab, on niisugune stabiilsus m\u00f5nev\u00f5rra \u00fcllatav.<\/p>\n

Varasemate uuringute j\u00e4rgi ongi teistele teadlastele tundunud, et need taevakehad kukuvadki peagi musta auku.<\/p>\n

<\/p>\n

\u00dcks neid uuritud ebatavalisi taevakehi kannab nime G2. Seda peeti varem lihtsakoeliseks gaasi- ja tolmupilveks, mis on Sagittarius A* raskusv\u00e4lja toimel piklikuks spagetiks veninud ja valmistub juba musta auku neelduma.<\/p>\n

N\u00fc\u00fcd aga ilmnes Euroopa L\u00f5unaobservatooriumi T\u0161iilis asuva V\u00e4ga Suure Teleskoobiga tehtud vaatlustel, et G2 orbiit on stabiilne. Sel puhul on ka eeldada, et selle gaasi- ja tolmupilve sees peidab end ka t\u00e4ht.<\/p>\n

Igal juhul tuleb m\u00f6\u00f6nda, et Linnutee kese ei pakugi mitte ainult tormilisi vaatem\u00e4nge ja tulev\u00e4rki, vaid ka kohatist stabiilsust. Ehk v\u00f5ib ka \u00f6elda, et Sagittarius A* on natuke v\u00e4hem hirmus kui seni arvatud.<\/p>\n

Ka kaksikt\u00e4hes\u00fcsteem nimega D9, mille Pei\u00dfker ja kolleegid mullu avastasid, trotsib \u00fclimassiivse musta augu \u00fcmber tiireldes selle \u00fcliv\u00f5imsaid loodej\u00f5ude ja p\u00fcsib stabiilne. Teooria j\u00e4rgi peaksid D9 osist\u00e4hed loodej\u00f5udude toimel \u00fcheks suureks t\u00e4heks kokku sulanduma.<\/p>\n

Ka t\u00e4heparved nimega X3 ja X7 tiirlevad stabiilsel orbiidil ja peavad seet\u00f5ttu olema vastupidavamad kui seni arvatud.<\/p>\n

Pei\u00dfker ja kaasautorid kirjutavad ajakirjas Astronomy & Astrophysics<\/a>, et Linnutee keskpiirkond on seni arvatust keerukam paik.<\/p>\n

Nad loodavad, et tulevastest vaatlustest, sealhulgas praegu veel rajamisel oleva Euroopa L\u00f5unaobservatooriumi Eriti Suure Teleskoobiga, saame paremini aru, miks Sagittarius A* toime oma \u00fcmbruskonna taevakehadele nii \u00fcllatavalt leebeks on osutunud.<\/p>\n

Pildil on \u00fclimassiivne must auk Sagittarius A* koos ta \u00fcmber p\u00f6\u00f6rleva kuuma gaasi kettaga kunstniku kujutuses.<\/p>\n
