Isithombe esisha se-“FS Tau star system” 

Isithombe esisha "sesistimu yenkanyezi ye-FS Tau" esithathwe yi- hubble Space I-Telescope (HST) ikhishwe ngomhla zingama-25 kuNdasa wezi-2024. Esithombeni esisha, amajethi avela kukhokhobe wenkanyezi esanda kwakheka ukuze aqhume ngaphesheya. isikhala, esika igesi nothuli lwe-nebula ekhanyayo.  

I-FS Tau inkanyezi Uhlelo luneminyaka engaba yizigidi ezingu-2.8 kuphela ubudala, luncane kakhulu ohlelweni lwezinkanyezi (iLanga, ngokuphambene, lineminyaka engaba yizigidi eziyizinkulungwane ezingu-4.6 ubudala). Iwuhlelo lwezinkanyezi eziningi olwakhiwe i-FS Tau A, into ekhanyayo efana nenkanyezi eseduze nendawo emaphakathi nesithombe, kanye ne-FS Tau B (Haro 6-5B), into ekhanyayo ekude kwesokudla esithwe kancane umgwaqo omnyama, oqondile wothuli. Lezi zinto ezincane zizungezwe igesi ekhanyiswa kancane kanye nothuli lwalesi sikhungo sezinkanyezi.  

I-FS Tau A ngokwayo iyisistimu kanambambili ye-T Tauri, ehlanganisa izinkanyezi ezimbili ukujikeleza ngabanye. 

I-FS Tau B iyinhlangano esanda kwakheka inkanyezi, noma i-protostar, futhi izungezwe idiski ye-protoplanetary, iqoqo lothuli negesi elimise okwekhekheba elisele ekwakhekeni kwenkanyezi okuzogcina kuhlanganela amaplanethi. Umzila owugqinsi wothuli, obonakala ucishe uphelele, uhlukanisa lokho okucatshangwa ukuthi yizindawo ezikhanyisiwe zediski. Kungenzeka ukuthi usenqubweni yokuba inkanyezi ye-T Tauri, uhlobo lwenkanyezi eguquguqukayo engakaqali i-nuclear Fusion nokho kodwa isiqala ukuguqukela ekubeni yinkanyezi ephehlwa yi-hydrogen njengeLanga.  

Ama-Protostars acwebezele ngamandla okushisa akhululwa njengoba amafu egesi asuka kuwo ewa, kanye nokunqwabelana kwezinto ezivela kugesi nothuli oluseduze. Izinkanyezi eziguquguqukayo ziyisigaba senkanyezi ukukhanya kwayo kushintsha ngokuphawulekayo ngokuhamba kwesikhathi. Baziwa ngokukhipha ukusakaza okusheshayo, okufana nekholomu yezinto ezinikezwa amandla ezibizwa ngokuthi amajethi, futhi i-FS Tau B inikeza isibonelo esimangalisayo salokhu. I-protostar iwumthombo we-asymmetric engajwayelekile, ijethi enezinhlangothi ezimbili, ebonakala lapha ngokuluhlaza okwesibhakabhaka. Ukwakheka kwayo okungalingani kungase kube ngenxa yokuthi ubuningi buyakhishwa entweni ngamanani ahlukene. 

I-FS Tau B iphinde ihlukaniswe njenge-Herbig-Haro into. Izinto ze-Herbig–Haro zakha lapho amajethi egesi e-ioned ekhishwa inkanyezi esencane eshayisana namafu aseduze egesi nothuli ngesivinini esiphezulu, nokudala amabala agqamile e-nebulosity. 

FS Tau inkanyezi Uhlelo luyingxenye yesifunda se-Taurus-Auriga, iqoqo lamafu amnyama angama-molecule ayikhaya lezinkanyezi eziningi ezisanda kwakheka nezincane, cishe ibanga leminyaka engu-450 yokukhanya kumaqoqo ezinkanyezi eTaurus nase-Auriga.  

I-Hubble Space Telescope (HST) uke waqaphela ngaphambilini u-FS Tau, umsebenzi wakhe wokwenza izinkanyezi okwenza kube okuphoqelekile okuqondiswe yizazi zezinkanyezi. hubble wenze lokhu kubheka njengengxenye yophenyo lwamadiski othuli azungeze izinto ezincane zezinkanyezi.
