Trans-Neptunian zvinhu: pfungwa, mhando

On kumucheto redu renzou ndiyo bhandi Kuiper. Anoenda achitsvaka Neptune kuti muchadenga, saka kumashure kuona chinhu muchadenga ichi zvave zvakaoma. Zvisinei, chero bedzi iripo munhu akaonekwa materesikopu simba, hazvina akakwanisa kuita zvinhu zvakawanda. Somuenzaniso, yakasvika pakuzivikanwa kuti mhiri-Neptunian zvinhu - inokosha chairema vanoumba ari Kuiper Belt, kuti Oort gore uye vakapararira Disc. Zvinokosha tikanyatsoongorora mumuviri, kutenderera mu "necheseri" ari renzou.

In redu renzou pane subclass iyi mhando miviri: vakanyarara chinhu. Akadana nokuti, tichitarisa zviri perihelion miviri yakadaro chiri panzvimbo rebei kure Neptune, saka haana kukanganiswa giravhiti kwayo. Izvi zvinoita mapuraneti aya anenge akazvimiririra, kwete chete kubva Neptune, asiwo kubva yose renzou yose.

Zvazviri, izvi zvinhu zviri miviri kumwezve dzakapfirirwa disk. Pari, mashoko anowanikwa vapfumbamwe miviri, asi mazita angangodaro munguva pfupi zvichaita kuti yekudyidzana kwakawedzera.

Classical Kuiper Belt Vanoramba

Zita boka iri miviri vakabva vakaverengwa wokutanga vavo - QB1. Ndokusaka mhiri-Neptunian zvinhu, riri muna Kuiper bhandi, akadana cubewanos (zano-bi-Ouen). The muchadenga izvi zvinhu nhema mhiri muchadenga pamusoro Neptune, nepo ivo vakaratidza kuva orbital resonance pamwe nyika.

Kutenderera dzakawanda cubewanos vane anenge dzeraundi chimiro pedyo ecliptic ndege. Chikamu chikuru mitumbi izvi achiratidza panguva vashomashoma yorusvingo, mumwe ane kurereka huru dzinoita uye yakawanda elongated kutenderera.

The chikuru zviri mitumbi vari boka iri zvinotevera:

• kutenderera avo haana piringisha ari muchadenga pamusoro Neptune.
• Zvinhu hazvisi resonant.
• eccentricity yavo - asingasviki 0.2.
• chokuratidza wavo Tisserand pane 3.

mumiririri Classic kuti boka iri - Quaoar, mumwe mitumbi kupfuura iri Kuiper Belt. It yakavhurwa 2002.

resonant TNO

Resonant mhiri-Neptunian zvinhu vaya vane muchadenga iri orbital resonance pamwe Neptune.

Kunyatsoongorora izvi zvinhu zvinoita kuti tikwanise kutaura pamusoro Kumanikana kwaiyoyi miganhu yacho resonant zvinhu. Kuti nguva dzose kuramba mukati mitemo iyi, muviri zvinoda mumwe yakawanda simba, pasisina uye hapana zvishoma. Onai kuti wakabuda muchadenga resonance, zviri nyore chaizvo, chete duku kutsauka kubva Semi-chikuru akabatana hwakagadzwa miganhu.

Sezvo Panovhurwa zvivako zvitsva yakawanikwa kuti kupfuura chegumi chazvo iri resonance 2: 3 ne Neptune. Zvinofungidzirwa kuti ukama hwakadaro hakusi netsaona. Ungangove, zvinhu izvi dzakatorwa pachishandiswa Neptune panguva kutama kusvikira kutenderera zvikuru kure.

Kutangira mhiri-Neptunian zvinhu, nyanzvi vaifunga kuti zvinoitwa nyika hombe iri hombe nemotokari kuchaderedza hafu mutsetse uye kuwedzera Semi-nematemo Jupiter Uranus, Neptune, uye Saturn yakavhurwa.

Mumwe vamiririri boka iri ndiyo Orc - mhiri-Neptunian zvinhu, iri Kuiper bhandi.

Vakapararira Disc zvinhu

Ichi ndicho muviri kuti vari kupfuura kure nharaunda redu renzou. The arambe achirema zvinhu munzvimbo iyi yakaderera zvikuru. dzakapfirirwa mitumbi yose Disc akaumbwa chando.

Mabviro nzvimbo iyi havana chaizvoizvo pachena. Masayendisiti Most vanowanzomuitira kudavira kuti yakaumbwa panguva apo rinokweva migumisiro mapuraneti kuonekwa kukwana zvainoita Kuiper Belt, saka kuti zvivako ayo akapararira pamusoro munzvimbo yakakura kupfuura nhasi. Akapararira dhisiki, zvichienzaniswa kuna Kuiper Belt - a chinji neChitatu. Muviri mairi vaifamba kwete chete "chinjikira" mirayiridzo, asiwo "kutwasuka", pamwe anenge chete kure. Computer Modelling kwakaratidza kuti zvimwe zvinhu angava meandering muchadenga, chikamu - kugadzikana. Izvi zvinoita kuti titi muviri anogona kusunungurwa kupinda Oort gore kana zvakawanda.

itsva kuwanikidza

In July 2016 zvakanzi vakawana mumwe mhiri-Neptunian zvinhu. miganhu yacho kwazvo diki (dhayamita - vanenge 200 km), ndiko 160 zviuru nguva fainter pane Neptune. zita rayo rinoshandurwa kubva Chinese rinoreva "kupandukira." Ndiro zita chinhu akagamuchira nokuti rotates nenzira chakatarisana kwebasa dzaro, sezvo izvi zvinogona kutsanangurwa chete chokuti chero muviri zvakakwana simba kufurira nayo, tangochinja muchadenga kwayo.

hunhu iri nzvimbo itsva waitwa masayendisiti kuti vakarasika, nokuda panguva hazvisi pachena kugona chii nyika uye kuti kuti "mupanduki" kufamba kwakadaro muchadenga. Vanodzidza nezvenyeredzi funga zvakare nezvokuvapo isingazivikanwi nyika, izvo zvinogona kudaro simba kukanganisa dzimwe miviri.
