Kpakpando nwụrụ anwụ na-ebibi usoro mbara ala
Ndị na-enyocha mbara igwe nke UCLA achọpụtala kpakpando dwarf na-acha ọcha nke na-eri ihe ndị na-egbuke egbuke, nke na-ekpo ọkụ. Achọpụtala na kpakpando, nke Ọ bụ afọ 86 ìhè site na Ụwa., na-amịkọrọ irighiri ihe site na ma n'èzí ma n'ime usoro. Naanị ikpe ndị gara aga nke anụ mmadụ nke ụwa egosila kpakpando na-agbapụta ihe sitere na mpụga sistemụ ya, mana dwarf ọcha a na-eri ihe sitere n'ime ma n'èzí sistemụ, na-atụ aro na ọ nwere ike ibibi usoro kpakpando ya niile.
Onye na-ede akwụkwọ na-ede akwụkwọ Ted Johnson, onye UCLA physics na astronomy nwa akwụkwọ, kwuru na ha na-atụ anya inweta nghọta ka mma banyere usoro mbara igwe site n'ịmụ dwarf ndị a na-acha ọcha. Kpakpando G238-44, nke dị nso na anyanwụ anyị, eriela kpakpando ndị ọzọ, dị ka data si Hubble Space Telescope na teliskop NASA ndị ọzọ si kwuo. Edepụtara ihe akaebe na nkwubi okwu dabere na nyocha nke ihe ndị weghaara ikuku kpakpando dị nso.
Mgbe kpakpando dị ka anyanwụ anyị agwụla mmanụ, ọ na-adaba n'ime kpakpando dwarf na-acha ọcha, nke na-adịkarị oke oke na nha nke mbara ala. Kpakpando na-agba hydrogen na cores ha, ma mgbe hydrogen gwụchara, ha na-ere helium n'ime isi ha. Mgbe kpakpando na-eme nke a, ọ ga-eto nke ọma nke na ọ ga-eloda mbara ala ya kacha nso.

Oge nke kpakpando na-eme mgbanwe a dị ukwuu, nke ọ nwere ike ịdịru 100 nde afọ, ọ nwere ike ịdị ize ndụ maka mbara ala dị nso. Ndị na-enyocha mbara igwe nke UCLA achọpụtala otu dwarf ọcha na-eripịa comet na asteroids. Kpakpando, nke dị n'afọ 86 site n'ụwa, na-agbapụta ihe site n'ime ma n'èzí usoro ya. Otu ndị na-enyocha mbara igwe na Mahadum California Los Angeles (USA) ahụla otu kpakpando dwarf ọcha nke na-eri asteroids na comet. Kpakpando ahụ na-amịkọrọ ihe site n'akụkụ elu na n'ime nke usoro ya, na-eme ka ọ bụrụ nke mbụ a hụrụ ụdị ihe abụọ dị iche iche nke eluigwe ka achịkọtara ọnụ na kpakpando dwarf na-acha ọcha n'otu oge.
Nchọpụta
Ted Johnson nwere olile anya na site n'ịmụ dwarf ndị a na-acha ọcha, anyị nwere ike nweta nghọta ka mma banyere usoro mbara ala ka dị. Telescope Hubble Space na ihe ndị NASA ndị ọzọ na-ahụ anya nyeere ndị na-enyocha mbara igwe aka ịmata ikpe nke mbụ nke anụ mmadụ nke mbara igwe nke kpakpando dwarf na-acha ọcha riri ma ihe na-acha oyi na-atụ na ihe nkume nkume. Nke a mere mgbe asteroid ma ọ bụ ahụ yiri ihe ndị dị na eriri Kuiper (disiki okirikiri nke mbara igwe nke dị n'èzí nke Neptune ma dị nso n'elu kpakpando anyị) jikọtara ya na White dwarf.
Emere nchọpụta a site n'ịtụle gas nke ikuku kpakpando weghaara. Kpakpando na-acha ọcha dwarf malitere mgbe obere kpakpando, dị ka anyanwụ anyị, gwụchara mmanụ nuklia. Kpakpando na-eji nwayọọ nwayọọ na-agba mmanụ ha ọkụ, na-eji hydrogen na isi ha. Mgbe hydrogen gwụchara, ha nwere ike iji helium n'ime isi ha na-aga n'ihu na-agbakọ. Mgbe kpakpando fụrụ elu wee ripịa mbara ala ya nso, ọ na-eme agadi ma na-eru ọgwụgwụ nke ndụ ya.

Kpakpando kacha ochie na-emecha ghọọ dwarf ọcha. Akara Kuiper bụ mpaghara juputara na ihe oyi, dị ka Arrokoth. N'ofe okirikiri Neptune dị eriri asteroid, ma karịa nke ahụ, mbara ala okwute. Ọ bụrụ na usoro mbara igwe anyị na-agafe oge mgbanwe ya (nke dị ihe dị ka nde afọ 100), kpakpando dwarf ọcha n'ọdịnihu ga-eri nri na foduru nke mbara ala ndị a, yana asteroids nke eriri asteroid.
Nchọpụta nke ikpe a nke anụ ọhịa nke eluigwe bụ ihe na-adọrọ mmasị n'ihi na ọ bụghị nanị na-egosi mgbanwe kpakpando a site na usoro mbara igwe anyị, ma n'ihi na asteroids na comets ndị a kwenyere na ha ejikọtala na Ụwa ọtụtụ ijeri afọ gara aga, na-ebute mmiri na mbara ala anyị, na-emepụta ezigbo ndụ. ọnọdụ.
