Kev muaj npe nrov - nws ... prominences rau lub hnub

Nyob rau hauv hnub ci kev ua si yog meant cov totality ntawm nraum phenomena, uas yog dynamically, thiab txawv active formations sawv nyob rau hauv lub hnub ci huab cua. Ib tug manifestation yog cov tsos ntawm nws cov kev ua si nyob rau hauv lub magnetic teb ntawm lub hnub ci huab cua tej fibers, namely - ntshav formations. Thaum lawv ua pom nyob rau ntawm ntug ntawm lub hnub ci disk, lawv hu ua prominences.

Prominences - yog dab tsi?

Tus thawj mention ntawm qhov tseeb hais tias thaum lub sij hawm tag nrho cov hnub ci dab noj hnub cai cov tsos ntawm txawv txawv formations, tau tshwm sim nyob rau hauv 1185, thiab ib tug tshawb kom ntxaws txog lawv pib nrog 1842. Tom qab ntawd lawv twb hu ua prominences (protubero), uas txhais los ntawm Latin txhais tau tias "swell."

Niaj hnub no, ua tsaug rau cov kev tshawb fawb heev heev, nws yog lub npe hu hais tias lub npe nrov - yog lub tsim ntawm lub hnub ci ntshav muaj enormous loj. Cov giant emissions sawv saum toj no qhov chaw ntawm lub hnub los ntawm cov kab ntawm kev quab yuam ntawm nws magnetic teb thiab yog muab khaws cia tseg muaj vim nws ib tug tej lub sij hawm. Ib txhia ntawm lawv tej zaum yuav "dai" nyob rau hauv lub hnub ci qhov chaw tej thaum mus txog rau ob peb lub hlis, suab tsis muaj kev hloov nyob rau hauv lawv cov thawj daim ntawv no.

Prominences nyob rau hauv qhov tseeb

Txawm tias muaj tseeb tias txoj kev tshawb ntawm cov txawv txawv formations ntawm science tau ib tug ntev lub sij hawm, tseeb thiab meej kev tshawb xav piav lawv muaj ntau haiv neeg thiab ntau yam tshwm sim txuam, yog tsis nrog lawv. Nyob rau hauv qhov tseeb prominences xwm - nws yog tsaus fiber, kom meej meej pom nyob rau hauv lub hnub lub chromosphere. Lawv cov qauv yog denser thiab txias tshaj lub puag ncig ntshav, thiab cov tshuaj nyob tus yeees ntawm lub teeb ntawm hais sib nug xov mus rau lawv txoj kev ua txheej. Cuaj kaum, lawv nrog cev mob xws li hais tias cov kab kev los ntawm ib co prominences oversaturated hydrogen kab, thiab lwm yam - nrog rau ntau yam hlau. Lub caij ntawm lawv lub neej qhia tau hais tias lawv yam khoom uas yog nyob rau ntawm magnetic rog.

Raws li prominences tshwm sim?

Hnub Ci prominences tshwm sim raws li kaj formations extending raws cov npoo ntawm cov hnub ci disk. Hnyuj hnyo rau nws tom qab, lawv muaj ib tug maub xim, uas yog vim qis tshaj lawv ncig, lawv ntshav kub.

Tiv thaiv lub keeb kwm ntawm lub kub corona muaj npe nrov - ib tug tuab thiab txias txoj kev ua. Rising ntawm tus nto ntawm lub hnub, nws yog cov resets nws substance, thiab ces cia thiab disappears. Ib txhia ntawm lawv yog cov tam sim no nyob rau hauv lub crown rau lub hlis, lwm leej lwm tus, mus rau ntawm kev kub ceev, tsis txhob ploj rau lub lim piam. Tib cov ntawv luam muaj zoo kawg li ceev, mam li nco dheev tawg.

Yuav ua li cas loj yog prominences?

Protuberances rau lub hnub hits nws extraordinary qhov ntev. Raug cov neeg sawv cev ntawm cov lug cuag ib tug qhov siab ntawm txog li 40 txhiab kilometers, thaum lawv dav tej zaum yuav txog 200 txhiab kis lus mev. Muaj kuj yog xws li emissions, lub qhov siab ntawm cov uas yog 800 txhiab kis lus mev. Pheej zaum tau sau tseg xws champions, qhov luaj li cas ntawm cov uas tshaj 3 million kilometers. Cov kev tawg ntawm ib qho ntawm tej loj loj prominences, uas tua, ru ib horseshoe, muaj cai nrog cov spacecraft rau 30 teev nyob rau hauv lub yim hli ntuj 2010.

Yuav ua li cas yog cov prominences?

Cov formations yuav ua tau heev ntau yam. Nyob rau hauv tsos thiab ceev ntawm prominences rau lub hnub muab faib ua:

• nqig, yus muaj los ntawm qeeb zog thiab cov luag imperceptible hloov rau hauv cov duab, tej zaum lawv yuav ua tau ib tug ob peb lub lis piam los yog lub hlis;
• active, cov tshuaj uas yog yus muaj los ntawm ceev ceev txaus thiab kav los ntawm ib tug ob peb feeb rau kaum ntawm cov sij hawm;
• tus khoos kas (coronal) feem ntau tshwm sim nyob rau hauv daim ntawv ntawm cov me me huab, uas nws thiaj li hauj lwm ua ke rau hauv ib tug loj huab uas tshwm sim rau ob peb teev;
• Eruptive (los yog noj tawm) zoo li loj loj chaw uas yuav tuaj sai sai heev thiab hloov nws zoo, thiab ces sai sai ploj.

Nyob ntawm seb lawv zoo lawm, raws li zoo raws li lub sijhawm nyob rau hauv uas lawv os nws tus kheej yog tsiv, lawv cov dej num rau hauv peb hom:

1. Kev kawm ntawv nyob rau hauv daim ntawv ntawm cov pa luam yeeb los yog huab dav hlau muaj peev xwm ntawm nce toj lub kauv rau ib tug txiav txim siab.
2. Protuberances nyob rau hauv daim ntawv ntawm cov nkhaus dav hlau thiab units uas pib thiab xaus rau ntawm lub hnub ci qhov chaw. Raws li ib tug txoj cai, raws magnetic teb kab, thaum muaj kev kub altitude lawv pib ploj mus.
3. Tsim kom muaj loj zoo li tus tsob ntoo los yog tsob nroj. Txhaws lawv tej khoom yuav tsiv mus nyob across, thaum muaj ib tug tshaj tawm uas tsis pub tshaj ib tug ob peb kaum ntawm km / s.

Yuav ua li cas mus soj ntsuam prominences?

Kev muaj npe nrov - yog ib tug manifestation ntawm hnub ci kev ua si. Saib nws yuav ua tau thaum lub sij hawm ib tug tag nrho hnub ci dab noj hnub, tab sis nws yog heev tsis tshua muaj. Yog vim li cas zaum tau raug ua lub tsev spectroscopic seev recreate dag cov dab noj hnub. Cov telescopes no yog ua los ntawm tshwj xeeb hom ntawm cov iav, devoid ntawm microbubbles muaj xws li ib tug dub disc, uas uas lub hli. Thaum lub sij hawm soj ntsuam ntawm lub hnub, nws maj mam slides dua nws, ua rau pab kiag li lawm pom tau qhov kaj emanating tsuas yog los ntawm nws crown.

Ua ntej lub qhov muag ntawm tus soj ntsuam muaj ib tug zoo daim duab - seev cev prominences rau lub hnub. Tshaj ntawd tus ntug ntawm lub makeshift hli kom meej meej pom projections ntawm complex zoo li ib tug kaj liab xim, zoo ib yam li nplaim taws los yog lossis loj huab escaping los ntawm cov sab sauv khaubncaws sab nraud povtseg ntawm cov hnub ci disk.

Tsis pub dhau ib tug 11-xyoo ncov ntawm hnub ci kev ua si yuav tsum tau cai coronal arc-zoo li tus protuberances. Nws tsis tshua muaj uas tsis yog-transferable kev zoo nkauj - lub tsim ntawm ib tug lossis loj huab, los ntawm uas sawv ntawm down kwj tshwm sim nyob rau hauv lub hnub ci corona saum toj no nws chromosphere.

Rau astronomers ntev tseem mysterious phenomena uas tshwm sim nyob rau hauv lub hnub ci corona. Kev muaj npe nrov ... Lo lus yog txuam nrog rau daim card cia lub hnub qub hu ua lub hnub. Thiab xwb tam sim no, ua tsaug rau satellites thiab chaw noj, feem ntau ntawm cov secrets tau qhia.

Tib neeg yuav ua kom muaj ntau yam ntxiv zoo kawg discoveries nyob rau hauv unexplored ntug thiab peb hnub ci system.
