Hubble Anobata 'Fireworks' Yakamutswa neKufa Kwechisimba kweStar

Mufananidzo unoshamisa zvechokwadi wakabudiswa neNASA unoratidza zvakasara zve supernova (kuputika kune simba kwakakonzerwa nekufa kwenyeredzi huru) yakatorwa neHubble Space Telescope.

Iri muLarge Magellanic Cloud, satellite galaxy yeMilky Way, marara anoumba maorenji neblue filaments akaomarara anoita senge fireworks.

Mitsara ine mavara egasi inopenya orenji nebhuruu mumufananidzo uyu zvisaririra zve supernova iyo yakaputika apo nyeredzi huru yakasvika kumagumo ehupenyu hwayo muLarge Magellanic Cloud. Credits: ESA/Hubble uye NASA, S. Kulkarni, Y. Chu

Inonzi DEM L-19 kana (LMC N49), iyo nyeredzi yakasara inogara makore angangoita 160.000 chiedza-makore kubva kuPasi muboka renyeredzi Dorado kumaodzanyemba kwehemisphere yedenga, uye inomiririra inopenya yakasara supernova mukati meLarge Magellanic Cloud. , masayendisiti eHubble akashuma mukati chirevo.

Kunyangwe maererano navo, aya mabhandi akatetepa zvakanyanya ezvinhu zvakasiiwa ne supernova anozopedzisira ave matombo ekuvaka kwechizvarwa chinotevera chenyeredzi mune iri boka renyeredzi.

Pamakore makumi manomwe nemashanu (75 light-years) kuyambuka, gore rinopenya rezvinhu rinovanza nyenyedzi yenyuturoni inokurumidza kutenderera yakagadzirwa apo mwongo wenyeredzi huru yaiputika wakadhirika pasi pekumanikidzwa kwakasimba kwemukati kwegiravhiti rayo pachayo.

Kunyangwe huremu hwenyeredzi hwenyuturoni hwakada kuenzana nehweZuva, hwakapfupikiswa zvakanyanya. "Yakakora, kutaura zvazviri, kuti teaspoon yezvinhu zviri mukati menyuturoni nyeredzi ingarema matani mabhiriyoni mana," masayendisiti anotsanangura kudaro, achibudisa pachena kuti chinhu chenyeredzi chakanyanya kukora chinotenderera kamwe chete mumasekonzi masere uye simba rayo remagineti rinenge. simba rakapetwa maquadrillion kupfuura magnetosphere yePasi.

Nyeredzi yenyutroni iyi yakawanikwa muna 1979 payakaburitsa kuputika kunoshamisa kwemwaranzi ine simba guru regamma. Kubva ipapo, mamwe akati wandei egamma-ray kuputika akaburitswa, achiiisa se "soft gamma-ray repeater" kana pulsar.

Verenga zvimwe:

Mufananidzo mutsva wakagadzirwa uchishandisa data kubva kune maviri akapatsanurwa DEM L-9 ongororo, imwe yaisanganisira ari pamudyandigere Wide Field Planetary Kamera 2 kubva kuHubble.

Zvinoenderana newebsite space.comOngororo iyi ine zvinangwa zviviri. Chikuru ndechekudzidza kuti supernova remnants inopindirana sei neiyo interstellar medium, guruva rakanaka pakati penyeredzi, muLarge Magellanic Cloud. Kunyanya, timu inoda kuziva kuti makore madiki egasi neguruva anoita sei kuti supernova yasara ishanduke uye ichinje chimiro chayo. Chinangwa chechipiri chechidzidzo ndechekudzidza gamma-ray inodzokorora yakavanzwa mukati megore.
