Inzululwazi ngeenkwenkwezi ibisoloko ibonwa njengentsimi apho kungekho nto inokuthathwa njengefanelekileyo, bekukho iingcinga ezininzi ezazibonakala zingenakuphikiswa ngelo xesha de iqela labaphandi likwazi ukufumanisa ubukho besenzeko esingazange sikwazi ukucinga esebenza ngokuchanekileyo ukutshabalalisa ithiyori ethile. Oku kuhlala kuyinto eyenzeka rhoqo nangakumbi ngokubulela kusetyenziso lweenkqubo ezinje nge-ALMA telescope, esivumela ukuba siqhubele phambili kumanqanaba amatsha olwazi.
Ngenxa yoku kwaye nangona kubonakala ngathi kunokwenzeka ukuba siyazi ukuba zenziwe njani iiplanethi, inyani kukuba sazi kancinci kunendlela esicinga ngayo kwaye kungcono ukugcina ujonge kwindawo engaphandle kolunye uhlobo lomfanekiso osincedayo ukuba siqwalasele indlela uhlobo lwendawo ephawulweyo esithubeni. Okokugqibela nasemva kwalo lonke eli xesha lokulinda sikwazile ukufumana umzuzu othile apho kubonakala ngathi Iiplanethi ezintathu ziqala ukubakho.
Iqela labaphandi lifumanisa iiplanethi ezintathu eziqala ukubakho
Ukufezekisa oku, iqela leenkwenkwezi lifune uncedo lwento ebizwa ngokuba yiteleskopu I-ALMA, Isixhobo esixhotyiswe ngee-eriyali ezichanekileyo ezingekho ngaphantsi kwamashumi amathandathu anesithandathu eziphaya kwithafa laseChajnantor (eChile) kungekho ngaphantsi kweemitha ezingama-5.000 XNUMX ngaphezulu komphakamo wolwandle. Umsebenzi odibeneyo walo lonke eli nani lee-eriyali kuthetha ukuba le nkqubo ingasebenza ngokungathi yiteleskopu enkulu, kungekuko ngelize sithetha ngeprojekthi ethi, ekuphuhlisweni nasekuqalisweni kwayo, ingafunanga nto ingaphantsi Utyalomali olungaphezulu kwesigidi se-euro.
Inyani yile yokuba ukuthetha ngesixa semali esityalwe ekwakheni iteleskopu eneempawu ze-ALMA kungoyikisa ngaphezulu kwesinye. Kwelinye icala, enkosi ngokuchanekileyo kule projekthi kuye kwakho nokwenzeka ukwenza inkqubela phambili kwezenzululwazi ezinjengezo zisidibanisayo namhlanje kule post, akukho nto ingaphantsi kokufunyanwa kweeplanethi ezintathu ezisandula ukwenziwa ezijikeleza inkwenkwezi HD 163296, inkwenkwezi ephindwe kabini ukuphakama njengeLanga lethu kodwa iminyaka yayo ikhulu leenkwenkwezi, kuba, ngokophando olwenziweyo, ineminyaka nje ezizigidi ezine ubudala.
Njengoko sinokufunda kwiphepha elipapashwe kwiphephancwadi Iincwadi zeeNcwadi ze-Astrophysical Ngeli qela labaphandi abazimeleyo, kuyacaca ukuba sithetha ngenkqubo entsha ebekwe kwikroza leSagittarius, malunga neminyaka engama-330 yokukhanya ukusuka eMhlabeni, umgama omangalisayo ongakhange ube ngumqobo kweli qela labaphandi. ekhokelwa nguRichard D. Teague, kusenokwenzeka ukuba wenze oku kufunyanisiweyo.
Ukutshintsha indlela idatha yokuqwalaselwa eqhutywa ngayo kukhokelele eli qela labaphandi ukuba bafumane iiplanethi ezintathu ezisandula ukwenziwa
Ukwazi ngakumbi ngakumbi ukuba ukufunyanwa okunje kwenziwa njani, xelela ukuba iqela labaphandi lithathe isigqibo sokuqhubeka ngendlela eyahlukileyo kufundo lwedatha ebonelelwa yi-ALMA kule nkqubo ukusukela, endaweni yokujonga ingaphakathi layo , njengoko kwenziwe ngamanye amaxesha, bagqiba kwelokuba bafunde igesi yediski ye-astro. Ngale ndlela baqaphela ukuba ukuhamba kwerhasi ngaphakathi kwenkwenkwezi, okuqhele ukulandela iphethini elula kwaye enokuxelwa kwangaphambili, kuphazamisekile, into eyenzeka kuphela phambi kwezinto ezinkulu.
Yile nto kanye eyakhokelela ukuba abaphandi bahlalutye ikhabhon monoksayidi esasazwa yidiski. Ngexesha lenkqubo bafumanisa ubukho bentshukumo engaqhelekanga ebonakala ngathi iyahambelana nobukho beeplanethi ezintathu ezisandula ukwenziwa. Ngokutsho koqikelelo lokuqala, kubonakala ngathi ezi planethi zingaba zi-12.000, 21.000 kunye ne-39.000 yezigidi zeekhilomitha ukusuka kwinkwenkwezi kwaye ziya kuba nemisa efanayo nezo zeJupiter.
Ngamazwi e Ipeyinti yeChistophe, Ukusuka kwiYunivesithi yaseMonash (Australia) kunye nombhali ophambili wesifundo:
Ukulinganisa ukuhamba kwerhasi ngaphakathi kwidiski yeprotoplanetary kusinika ukuqiniseka ngakumbi malunga nobukho beeplanethi ezijikeleze inkwenkwezi encinci. Obu buchule bunikezela ngendlela entsha ethembisayo yokuqonda ukuba zenzeka njani iinkqubo zeeplanethi.
