description

Daya daga cikin na farko kimiyya ambaci prominences hade da wani kallon masassarar rana, wanda ya faru a 1185. Amma saboda da ajizanci na kayan aiki da kuma rauni ci gaba da kimiyya nazarin astrophysics martabar fara a tsakiyar XIX karni. A 1868, Per Zhansen, ta amfani da wani sabon Hanyar kiyaye wannan sabon abu ba tare da wani kallon masassarar rana, ya zo ga ƙarshe cewa sun zama a wani gaseous jihar.

By su yanayi, prominences - shi ne wani abu da zai iya da kyau koyi ne kawai ta amfani da nasarorin da kimiyya da kuma fasaha ci gaba: lokaci-lapse da kuma wucin gadi Duniya kallo da tauraron dan adam.

Su ne a fili bayyane a lokacin da hasken rana eclipses, cike da hali. Domin irin wannan mamaki da aka lura ta wajen musamman na'urorin: martabar nesa tace coronagraph, chromospheric nesa da sauran. Idan muka yi la'akari da tsinkaya daga cikin prominences a kan hasken rana faifai, da suka bayyana a matsayin duhu, elongated zaruruwa mai sãɓãnin kauri. Saboda haka prominences - wani sabon abu da tare da wata al'ada kawo nesa kusa kawai a lokacin da wani total kallon masassarar rana za a iya lura.

Domin cewa irin wannan hasken rana prominences, a gaskiya, mun fahimci, yanzu la'akari da ra'ayoyinsu.

iri

Idan muka magana game da bayyanar, da prominences - a wispy Tsarin kama zaren, ko clots na jini daban-daban siffofi. Har ila yau, suna kullum motsi da kuma canza siffar. Su rarrabuwa da aka yi da tsauri ko morphological fasali. La'akari da su rarrabuwa da irin bayyanar, siffofi na motsi na al'amarin, kuma gudun:

• Kwantar da hankula. Su kome motsa more sannu a hankali. A tsari kuma canza sosai a hankali. Idan muka magana game da lokacin da rayukansu, shi jeri daga makonni da dama zuwa watanni da dama. Akwai a duk heliographic latitudes. Mafi sau da yawa da suka za a iya lura kusa sunspots marigayi mataki na ci gaba. Zafin jiki ne game da 15 000 digiri Celsius.
• Active. Wannan martabar hoto wanda za a iya gani a kasa, halin a cewa jini yana kwaranya daga kasa zuwa wajen geyser photosphere da daya protuberance zuwa wani mataki a sosai high gudun. su zafin jiki ne 25,000 digiri Celsius. Kuma ta hanyar, da yawa aiki prominences aka kafa daga natsuwa, amma a wannan yanayin, lokacin da suka zama ne daga dama da minti zuwa kwanaki.

• Eruptive. Idan muka magana game da bayyanar, mafi irin protuberances kama babbar marmaro tsawo na fiye da rabin miliyan kilomita sama da surface na mu star. Gudu da jini ya kai wani mutum ɗari kilomita awa, kuma su siffar da aka canza sosai da sauri. Akwai short-rayu, da kuma tare da karuwa a tsawo hankali dissipate gaba daya.
• Looping prominences s bayyana a cikin hanyar kananan sararin sama, da chromosphere. Yawanci, sun ƙarasa da ci a cikin daya manyan girgije, wanda sa'an nan fitarda wajen chromosphere zafi gas jet. Akwai irin mamaki da wuya fiye da 'yan sa'o'i.

Saboda haka a yanzu mun san cewa da hasken rana Corona yana prominences da kuma abin da ra'ayoyi akwai.

A ka'idar bayyanar

Duk da cewa da hasken rana aiki ne karatu na dogon lokaci, a hadade da cikakken ka'idar, wanda zai bayyana hakikanin abin da ya faru na prominences da kuma duk sauran related mamaki, ba tukuna. Part dukkan wannan yana bayyana da hadin gwiwa mataki na lantarki da kuma Magnetic karfi da karfi na nauyi na rana.

A sunadarai abun da ke ciki na martabar fili yayi dace da Layer daga abin da aka kafa. Amma tare da sinadaran abun da ke ciki na da ala da jiki yanayi na zama na sabon abu. Alal misali, da bakan aka mamaye hydrogen shiru prominences layi ionized alli. A waɗannan dangantawa da sunspots, mafi fili alama Lines na daban-daban karafa.

Gaskiyar shafe tsawon zama na wasu jinsunan da shawara cewa, da abu dauke da Magnetic karfi daga cikin taurãri. Wannan zato aka tabbatar da wani yawan spectroscopic lura.

hadari

Kamar yadda muka riga tattauna, martabar - wani aiki kashi na chromosphere rãnã da wasu daga ta jiki matakai. Da farko hadari, sũ ne waɗanda cewa karya daga surface da garken taurari a interstellar sarari. Dangane da ƙarfi, ba za su iya musaki da tauraron dan adam a Duniya madawwama biyu, kuma ko da kashe da ISS ƙungiya. Reacts tare da magnetosphere na duniya tamu, prominences kuma samar m Magnetic hadari da shafi alheri weather-m mutane, tsoma baki da rediyo sadarwa da kuma tsarin daban-daban kayan lantarki. Abin farin, prominences, wanda suke iya karya daga Sun ta surface da kuma haifar da irin wannan lalacewar, su ne musamman rare.

Amma idan mun yi la'akari da mafi m zaɓi lokacin da martabar zai yi babban size, shi iya mai tsanani lalata yanayi na duniya tamu, ko hallaka dukan rai da kõme.
