'Yan sandan Black Hole' sun Gano Bakar Hole mai Barci A Wajen Galaxy Mu

Tawagar ƙwararrun ƙwararrun ƙwararrun ƙasashen duniya da suka yi suna don yin watsi da bincike-bincike na black hole da yawa sun gano wani babban rami mai duhu a cikin Babban Magellanic Cloud, galaxy maƙwabta da namu. "A karon farko, ƙungiyarmu ta taru don ba da rahoton wani binciken da aka gano baƙar fata, maimakon ƙin yarda da shi" In ji jagoran binciken Tomer Shenar. Bugu da ƙari, sun gano cewa tauraron da ya haifar da baƙar fata ya ɓace ba tare da wata alamar fashewa mai karfi ba. An gudanar da binciken ne saboda shekaru shida na lura da aka yi tare da na'urar hangen nesa ta Kudancin Turai (ESO) Very Large Telescope (VLT).

"Mun gano wani 'allura a cikin hay'" In ji Shenar, wacce ta fara karatu a KU Leuven da ke Belgium, kuma a yanzu ta kasance abokiyar aikin Marie-Curie a Jami’ar Amsterdam da ke Netherlands. Yayin da aka ba da shawarar wasu 'yan takara masu kama da baƙar fata, ƙungiyar ta yi iƙirarin cewa wannan shine farkon 'barci' mai baƙar fata da aka gano ba tare da wata shakka ba a wajen tauraron mu. suna samuwa a lokacin da manyan taurari suka kai ƙarshen rayuwarsu kuma suna rushewa ƙarƙashin nasu nauyi. A cikin tsarin binary, tsarin taurari biyu suna jujjuya juna, wannan tsari yana barin bayan wani baƙar fata mai kewayawa tare da tauraro mai haske. Baƙin rami yana 'barci' idan ba ya fitar da matakan X-ray mai yawa, wanda shine yadda ake gano waɗannan baƙar fata.

"Abin mamaki ne cewa kusan ba mu san game da ramukan baƙar fata ba, idan aka yi la'akari da yadda masana ilimin taurari suka yi imani da su." ya bayyana mawallafin marubuci Pablo Marchant na KU Leuven. Sabon baƙar fata da aka gano ya kai aƙalla ninki tara na yawan Rana, kuma yana kewaya tauraro mai zafi, shuɗi, sau 25 fiye da girman Rana.

Baƙaƙen ramukan barci suna da wahalar ganowa musamman saboda ba sa mu'amala da mahallinsu. "Mun kasance muna neman waɗannan tsarin binary black hole sama da shekaru biyu" In ji mawallafin marubuci Julia Bodensteiner, mai binciken ESO a Jamus. "Na yi matukar farin ciki lokacin da na ji labarin VFTS 243, wanda a ganina shi ne dan takara mafi tursasawa da aka ruwaito."

Don nemo VFTS 243, haɗin gwiwar ya bincika kusan manyan taurari 1000 a cikin yankin Tarantula Nebula na Babban Magellanic Cloud, yana neman waɗanda za su iya samun ramukan baƙi a matsayin abokai.

"A matsayina na mai bincike wanda ya yi watsi da ramukan baƙar fata a cikin 'yan shekarun nan, na yi matukar shakka game da wannan binciken," in ji Shenar. Mawallafin Kareem El-Badry na Cibiyar Nazarin Astrophysics ya raba wannan shakka | Harvard & Smithsonian a Amurka, wanda Shenar ya kira "mai lalata rami mai duhu". "Lokacin da Tomer ya neme ni in bincika bincikensa, na yi shakka. Amma ba zan iya samun bayani mai ma'ana ba game da bayanan da bai ƙunshi rami mai baki ba." ya bayyana El-Badry.

Binciken ya kuma ba ƙungiyar duba hanyoyin da ke tare da samuwar baƙar fata. Masana ilmin taurari sun yi imanin cewa baƙar fata mai tauraro yana tasowa lokacin da ainihin babban tauraro da ke mutuwa ya faɗi, amma har yanzu babu tabbas ko wannan yana tare da fashewar supernova mai ƙarfi ko a'a.

"Tauraron da ya kafa baƙar fata a cikin VFTS 243 ya bayyana ya rushe gaba ɗaya, ba tare da alamar fashewar da ta gabata ba." ta bayyana Shenar. “Shaida kan wannan yanayin ‘rushewar kai tsaye’ ya bayyana kwanan nan, amma wataƙila bincikenmu yana ba da ɗaya daga cikin alamun kai tsaye. Wannan yana da babban tasiri ga asalin haɗin gwiwar black hole a cikin sararin samaniya."

An samo baƙar fata a cikin VFTS 243 ta amfani da shekaru shida na lura da Tarantula Nebula ta kayan aikin Fiber Large Array Multi Element Spectrograph (FLAMES) akan ESO's VLT. a yau a cikin ilmin taurari na yanayi, zai ba da damar gano wasu taurarin taurari masu tarin yawa da ke kewaye da manya-manyan taurari, wadanda aka yi hasashen dubbansu a cikin Milky Way da Magellanic Clouds.

"Tabbas, ina fata wasu a cikin filin za su yi bitar bincikenmu a hankali kuma su yi ƙoƙari su fito da wasu samfura." ya kammala El-Badry. "Aiki ne mai ban sha'awa sosai don shiga ciki."
