Izimbobo ezimnyama bezilokhu zidonsa ukunaka kwabo bobabili ososayensi kanye nomphakathi jikelele. I-European Southern Observatory (ESO) imemezele ukutholakala kwembobo emnyama yenkanyezi enkulu kunazo zonke ezake zatholakala ku-Milky Way.

Kulesi sihloko sizokutshela konke odinga ukukwazi mayelana ukutholwa komgodi omkhulu omnyama ku-Milky Way.

yini imbobo emnyama

umgodi omnyama

Imbobo emnyama isifunda sesikhathi sasemkhathini lapho amandla adonsela phansi ashube kangangokuthi akukho lutho, ngisho nokukhanya, okungabalekela ukudonsa kwawo. Sakheka lapho inkanyezi enkulu iwa ngaphansi kwesisindo sayo ekupheleni komjikelezo wayo wokuphila.

Esinye sezici eziphawuleka kakhulu zemigodi emnyama ubunye bawo obudonsela phansi.. Phakathi nendawo ebizwa ngokuthi umkhathizwe womcimbi, amandla adonsela phansi anamandla kangangokuthi akukho lutho olungasuka, ngisho nokukhanya. Lokhu kudala uhlobo lomngcele ongabonakali ngale kwalokho singakwazi ukubona noma ukubona lutho.

Izimbobo ezimnyama ziza ngobukhulu obuhlukahlukene. Ezincane kakhulu, ezaziwa ngokuthi ama-primordial black holes, zingaba nesisindo se-asteroid kodwa zicindezelwe zibe isikhala esincane ngendlela emangalisayo. Ngakolunye uhlangothi, kunemigodi emnyama emikhulu kakhulu, etholakala enkabeni yemithala eminingi, kuhlanganise nowethu i-Milky Way. Lezi zingaba nezixuku ezilingana nezigidi noma ngisho nezigidigidi zezikhathi zeLanga.

Isici esiyinhloko sezimbobo ezimnyama ubunye bazo, indawo yokuminyana okungapheli lapho imithetho eyaziwayo yefiziksi ingasasebenzi. Kodwa-ke, ubunye bugoqwe emkhathizwe womcimbi, okusho ukuthi, ngaphandle, Imbobo emnyama ibonakala inosayizi olinganiselwe futhi ochaziwe.

Ngaphezu kobuningi bazo, izimbobo ezimnyama zibonakala ngokujikeleza kwazo. Uma inkanyezi iwa ngokulinganayo, umgodi omnyama ophumelayo ungaphenduka. Lokhu kuzungezisa kuthinta ukwakheka kwesikhathi sesikhala esisizungezile, okuvumela imbobo emnyama ukuthi idonse into eseduze namandla ngayo.

Ukukhishwa kwemisebe emgodini omnyama, owaziwa ngokuthi imisebe ye-Hawking, kungesinye isici esithakazelisayo. Ngokombono ohlongozwe uStephen Hawking, izimbobo ezimnyama azimnyama ngokuphelele, kodwa kunalokho zikhipha isilinganiso esincane semisebe eshisayo ngenxa yemiphumela ye-quantum eduze nendawo yazo yomcimbi.

Bathola imbobo emnyama enkulu kunazo zonke eMilky Way

umgodi omkhulu omnyama

I-European Southern Observatory (ESO) imemezele ukutholakala kwembobo emnyama yenkanyezi enkulu kunazo zonke ezake zatholakala ku-Milky Way. Izazi zezinkanyezi zithole imbobo emnyama enesisindo esiphindwe izikhathi ezingu-33 kune-Sun, zisebenzisa idatha evela kumishini ye-Gaia. I-Gaia, indawo yokubuka umkhathi esetshenziswa yi-European Space Agency (ESA), Inesibopho sokuqoqa ulwazi emzileni womhlaba ukuze kwakhiwe imephu enezinhlangothi ezintathu enemininingwane eminingi nenembile yomthala wethu, i-Milky Way.

Besebenzisa idatha eqoqwe yisibonakude esikhulu ngokuphawulekayo se-ESO nezinye izindawo zokubuka izinto ezisekelwe eMhlabeni, ososayensi bakwazile ukuqinisekisa isisindo somgodi omnyama, okumangazayo ukuthi silingana nesisindo seLanga lethu izikhathi ezingu-33 "kokuzamazama" okukhishwa imbobo emnyama kunkanyezi ehambisana nayo ku-orbit. Izimbobo ezimnyama ze-Stellar zizalwa kusukela ekuweni kwezinkanyezi ezinkulu, futhi lezo ezikhonjwe kuze kube manje ngaphakathi kwe-Milky Way zivame ukuba mkhulu ngokuphindwe ka-10 kuneLanga lethu, ngokwesilinganiso.

Okutholwe muva nje kuyamangalisa ngempela, kudlula ngisho nembobo emnyama yenkanyezi enkulukazi eyaziwayo emthaleni wethu, i-Cygnus X-1, enesisindo esiphindwe izikhathi ezingu-21 kuphela kunelanga lethu. Ngaphezu kwalokho, kuyaphawuleka ukuthi lo mgodi omnyama useduze kakhulu noMhlaba, ibanga leminyaka engu-2.000 XNUMX nje yokukhanya, futhi uhlala emlaza i-Akwila. Kuyaphawuleka ukuthi lo mgodi omnyama ungowesibili oseduze kakhulu ohlonziwe kuze kube manje.

Phakathi nenqubo yokubuyekeza okuphawulwe yi-Gaia ngokulindela ukukhishwa kwedatha okuzayo, ithimba lazithela kumgodi omnyama wobukhulu obuseduze obungatholakali. Le mbobo emnyama esanda kukhonjwa, eyaziwa ngokuthi i-Gaia BH3 noma i-BH3 ngamafuphi, yamangala wonke umuntu. UPasquale Panuzzo, isazi sezinkanyezi eParis Observatory futhi oyilungu lokubambisana kweGaia, oxhumene neNational Center for Scientific Research (CNRS) yaseFrance, Uzwakalise ukumangala ngokutholakala kwakhe wathi akekho oseke wabona kusengaphambili ukuthi umgodi omnyama onjalo kuze kube manje.

Egcizelela ukutholakala kwento enjalo emsebenzini wocwaningo, wagqamisa ukubaluleka kwalokhu kutholakala. Ngaphambilini izazi zezinkanyezi ziye zahlonza izimbobo ezinkulu ezimnyama ngale komthala wethu futhi zaphakamisa ukuthi zisuka ekuqhumeni kwezinkanyezi ezinezakhi ezincane ezisindayo kune-hydrogen ne-helium. Lezi zinkanyezi, ezingenazo izinsimbi, kukholakala ukuthi zigcina isisindo esiningi kukho konke ukuphila kwazo, okuholela ekwakhekeni kwezimbobo ezimnyama ezinobukhulu obukhulu ngemva kokushona kwazo. Nokho, Kuze kube manje abukho ubufakazi obuphathekayo obusungula ukuxhumana okuqondile phakathi kwezinkanyezi ezintula insimbi nezimbobo ezimnyama ezinobukhulu obukhulu.

Itholakala kuphi?

Ngokwesitatimende esivela eNyuvesi yaseGeneva (Switzerland), umgodi omkhulu omnyama ungaphakathi komlaza woKhozi. Lokhu okutholakele okumangalisayo kudlula wonke amarekhodi angaphambili osayizi wezimbobo ezimnyama ezibonwa ngaphakathi komthala wethu, njengoba ubukhulu bazo buphindwe izikhathi eziyishumi kobezinkanyezi bethembele kudatha eqoqwe kuma-observatories asekelwe phansi ukuze kuqinisekiswe lokhu kutholwa.

Ithuluzi eligqama kakhulu i-UVES (Ultraviolet and Visual Echelle Spectrograph) etholakala ogwadule lwase-Atacama, eChile. Injongo yaso iwukubona ukunyakaza okunembile kwezinkanyezi ezingaphezu kwezigidi eziyizinkulungwane ezimbili esibhakabhakeni ukuze zikale ngokunembile amabanga azo.

Emkhakheni wokutholwa kwemigodi emnyama kuze kube manje, umphakathi wesayensi uye wanquma ngokuyinhloko ukuthi kungenzeka ukuthi zisuka ekuweni kwamandla adonsela phansi ezinkanyezi, ezakhiwe ngokuyinhloko i-hydrogen ne-helium enezinto ezincane ezisindayo. lUmbono wokuthi lezi zimbobo ezimnyama zingagcina isisindo esiphansi ungase ube yinkomba yokwakhiwa kwezimbobo ezinkulu ezimnyama. Ubukhulu balezi zinkanyezi ezintula umphumela wokwakhiwa kwama-void amakhulu ngenxa yobuningi bezinto ezisele. Ngaphezu kwalokho, abacwaningi bagcizelele ukuthi kuze kube manje abukho ubufakazi obuphathekayo obusungula ukuxhumana okuqondile phakathi kwezinkanyezi ezimpofu zensimbi nezimbobo ezimnyama.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokutholakala komgodi omkhulu omnyama ku-Milky Way.
