Binciken DART na NASA, wanda da gangan yayi karo da asteroid Dimorphos a cikin Satumba 2022, ya ba da shaidar gani kai tsaye cewa asteroids a cikin tsarin binary suna musayar abu da juna. Imagens wanda kyamarar DRACO ta bincike ta ɗauka ta bayyana alamun ɗamara mai haske a saman Dimorphos. Esses alamu sun bayyana bayan aiki don kawar da inuwa da bambancin haske. Cientistas ya gano cewa al’amarin ya samo asali ne daga karon ƙananan gudu, idan aka kwatanta da wasan ƙwallon ƙanƙara da aka ƙaddamar daga Didymos zuwa ƙaramin abokin sa.
Tasirin DART ya canza kewayawar Dimorphos a kusa da Didymos a cikin mintuna 33, yana tabbatar da yuwuwar fasahar motsin motsi. Tsarin binary, tare da Didymos kimanin mita 780 a diamita da Dimorphos kimanin mita 160 a diamita, yana wakiltar samfurin gama gari tsakanin asteroids kusa da Terra. Fitar da kayan a lokacin tasirin ya saki miliyoyin kilogiram na duwatsu da ƙura. Sakin Essa ya ba da gudummawa ga haɓakar haɓaka kusan kusan biyu, yana ninka tasirin tasirin binciken.
Abubuwan da aka gani a saman Dimorphos
Makada masu siffar fan a saman Dimorphos suna nuna adibas na kaya daga Didymos. Gyaran hoto yana gyara tasirin hasken wuta da inuwar da duwatsu ke jefawa. Samfuran sun ƙunshi alamomi masu hankali waɗanda suka daidaita tare da tasirin ƙarancin kuzari.
Masana kimiyya daga Universidade da Maryland sun jagoranci bincike kuma sun tabbatar da dacewa tare da saurin karo a kusa da 30.7 cm/s. Experimentos dakunan gwaje-gwaje tare da yashi da tsakuwa sun sake haifar da irin wannan ajiya ba tare da samuwar ramuka ba.
Tasirin YORP yana motsa fitar da kayan
Tasirin YORP, wanda ke haifar da hasken rana da ƙarfin zafi, yana haɓaka jujjuyawar asteroids. Essa acceleration yana haifar da runduna ta tsakiya waɗanda ke fitar da duwatsu da ƙura daga saman Didymos. Parte na wannan abu yana bin hanyoyin da ke haifar da tasiri mai laushi akan Dimorphos.
Binciken yana wakiltar shaidar gani ta farko kai tsaye na jigilar kayan kwanan nan a cikin tsarin binary. Modelos ƙididdiga suna goyan bayan samuwar waɗannan sifofi ta hanyar karon ƙananan sauri.
Abubuwan da ke haifar da tsarin asteroid binary
Tsarin kamar Didymos-Dimorphos sun ƙunshi kusan 15% na asteroids kusa da Terra. Ci gaba da musanya kayan abu yana tasiri juyin halitta sama da miliyoyin shekaru. Ayyukan Esses suna gyara sifofi da abubuwan da ke jikin jiki.
Gano ajiyar kuɗi a cikin Dimorphos yana ba da shawara mafi girma a cikin waɗannan tsarin fiye da zato a baya. Estudos ƙila na gaba na iya daidaita abubuwan da ke tattare da jujjuyawa.
Ci gaba a cikin tsaron duniya
Manufar DART ta gwada hanyar karkatar da asteroids ta hanyar tasirin motsa jiki. Fitar da aka yi a yayin karon ya faɗaɗa fahimtar abin da ke faruwa a lokacin. Bayanan Esses yana taimakawa inganta dabarun yaƙi da masu yuwuwar barazanar.
Ƙarin bincike ya haɗa abubuwan lura don inganta tasirin tasiri. Dabarar tana nuna tasiri mai amfani a canza yanayin.
Bayanan fasaha na hotunan da aka sarrafa
Sarrafa ya haɗa da gyaran albedo don haskaka bambance-bambance masu sauƙi a saman. Direban suna bayyana azaman tsarin fan wanda yayi daidai da yanayin ɓangarorin da aka fitar. Análises ya haramta kayan aikin kyamara ko hasken da bai dace ba.

Kwatanta tare da fitar da tasirin DART
Tasirin binciken ya haifar da fitar da tarkace cikin sauri. Sabanin haka, musayar dabi’a na faruwa a cikin sauri da sauri. Alamu a cikin Dimorphos sun samo asali ne daga matakai a hankali ba daga taron 2022 ba.
Ƙarin abubuwan dubawa tare da na’urorin hangen nesa kamar Hubble sun bi diddigin duwatsun da aka harba a cikin gudun kusan kilomita 1 / h. Bayanan Esses yana ƙarfafa bambance-bambance tsakanin hanyoyin halitta da na wucin gadi.
