The findings indicate that at least somerogue planetsmayshareasimilarformationpathtostars since similar bursts of accretion have been spot- ted in young stars before. As co-author Belinda Damian, also an astronomer at the University of StAndrews,explains: “Thisdiscoveryblurstheline between stars and planets and gives us a sneak peekintotheearliestformationperiodsofrogue planets.” By comparing the light emitted before andduringtheburst,astronomersgathered clues JANUARY-FEBRUARY2026 ﻣﺠﻠﺔ FreeAstronomy ﺎﻟﻌﺮ ﺔ 9 واﻟﻜﻨﺪﻳﺔ ﺑﺎﻹﺿﺎﻓﺔ إﱃ ﺑﻴﺎﻧﺎت أرﺷﻴﻔﻴﺔ ﻣـﻦ ﻣﻘﻴـﺎس اﻟﻄﻴـﻒ ﻋﲆ ﺳﻴﻨﻔﻮﻧﻲ اﻟﺘﻠﺴﻜﻮب اﻟﻜﺒ ﺟﺪاً اﻟﺘﺎﺑﻊ ﻟﻠﻤﺮﺻﺪ اﻷوروﺑـﻲ اﻟﺠﻨﻮﺑﻲ ﻻ . ﻳﺰال أﺻﻞ اﻟﻜﻮاﻛﺐ ا ﻟﺸﺎردة ﺳﺆاﻻً ﻣﻔﺘﻮﺣـ : ﺎً ﻫـﻞ ﻫﻲ اﻷ ﺟﺴﺎم ذات اﻟﻜﺘﻠﺔ اﻷﻗﻞ اﻟﺘﻲ ﺗﺘﻜﻮن ﻣﺜﻞ اﻟﻨﺠﻮم أم أﻧﻬـﺎ ﻛﻮاﻛﺐ ﻋﻤﻼﻗﺔ ﻃ ﺮدت ﻣﻦ أﻧﻈﻤﺔ ﻧﺸﺄﺗﻬﺎ؟ ﻫﻜﺬا ﻳﺴﺄل أﻟﻴﻜﺲ ﺷﻮﻟﺘﺰ أﺣﺪ ا ﺸﺎرﻛ ﰲ ﺗﺄﻟﻴﻒ اﻟﺪراﺳﺔ وﻋﺎﻟﻢ ﻓﻠـﻚ ﰲ ﺟﺎﻣﻌـﺔ ﺑ ﺳﺎﻧﺖ أﻧﺪروز ﺎ ﻤﻠﻜﺔ ا ﺘﺤﺪة . ﺗﺸ اﻟﻨﺘﺎﺋﺞ إﱃ أن ﺑﻌﺾ اﻟﻜﻮاﻛﺐ ا ﺎرﻗﺔ ﻋﲆ اﻷﻗﻞ ﻗﺪ ﺗﺸﱰك ﰲ ﻣﺴﺎر ﺗﻜﻮن ﻣﺸﺎﺑﻪ ﻟﻠﻨﺠﻮم إذ ﻟﻮﺣﻈﺖ اﻧﻔﺠﺎرات ﻣﻤﺎﺛﻠﺔ ﻣﻦ أﺣﺪاث اﻟﱰاﻛﻢ ﻟﺪى اﻟﻨﺠﻮم اﻟﺸﺎﺑﺔ ﺳﺎﺑﻘ . ﺎً ـ وﻛﻤﺎ ﺗ ﴩح ﺑﻴﻠﻴﻨﺪا داﻣﻴﺎن أﻳﻀ ﺎ ﻋ ﺎ ـﺔ اﻟ ﻔﻠـﻚ ﰲ ﺟﺎﻣﻌـﺔ ﺳـﺎﻧﺖ أﻧـﺪروز ﻫـﺬا ": اﻻﻛﺘﺸﺎف ﻳﻄﻤـﺲ اﻟﺨـﻂ اﻟﻔﺎﺻـﻞ ﺑـ اﻟﻨﺠـﻮم واﻟﻜﻮاﻛـﺐ وﻳﻤﻨﺤﻨﺎ ﺤﺔ ﻋﻦ ا ﺮا ﺣﻞ اﻷوﱃ ﻟﺘﻜﻮّن اﻟﻜﻮاﻛﺐ اﻟﺸﺎردة ﻣﻦ “ . ﺧﻼل ﻣﻘﺎرﻧﺔ اﻟ ﻀﻮء ا ﻨﺒﻌﺚ ﻗﺒﻞ وأﺛﻨﺎء اﻻﻧﻔﺠﺎر ﺟﻤﻊ ﻋﻠﻤـﺎء اﻟﻔﻠﻚ أدﻟﺔ ﺣﻮل ﻃﺒﻴﻌﺔ ﻋﻤﻠﻴﺔ اﻟﱰاﻛﻢ وﻣﻦ اﻟﻼﻓﺖ أن اﻟ ﻨﺸـﺎط ا ﻐﻨﺎﻃﻴﴘ ﺑـﺪا أﻧـﻪ ﻟﻌـﺐ دور ﰲ اً دﻓـﻊ ﺗـﺪﻓﻖ ا ـﺎدة ﺑﺸـﻜﻞ دراﻣﺎﺗﻴﻜﻲ وﻫﻮ أﻣﺮ ﻟﻮﺣﻆ ﺳﺎﺑﻘ ﺎً ﻓﻘﻂ ﰲ اﻟﻨﺠﻮم . ﻫﺬا ﻳﺸـ إﱃ أن ﺣﺘــﻰ اﻷﺟــﺮام ﻣﻨﺨﻔﻀــﺔ اﻟﻜﺘﻠــﺔ ﻳﻤﻜــﻦ أن ﺗﻤﺘﻠــﻚ ــــــــــــــــــــــ https://www.eso.org/public/unitedkingdom/videos/eso2516a/ اﻛﺘﺸﻒ ﻋﻠﻤﺎء اﻟﻔﻠﻚﻃﻔﺮة ﻧﻤﻮّ ﻋﻨ ﻔﺔ ﻓﻲ ﻮﻛﺐٍ - ﺷﺎرد أي ﻮﻛﺐ ﻻ ﺪورﺣﻮل ــــﻢ ﻧ وﻗـــــﺪ ﻛﺸــــﻔﺖ أرﺻـــــﺎد أُﺟﺮ ـــــﺖ ﺎﺳــــﺘﺨﺪام اﻟﺘﻠﺴـــــ ﻮب اﻟﻜﺒـــــ ﺟــــﺪ اً اﻟﺘـــــﺎﺑﻊ ﻟﻠﻤﺮﺻـــــﺪ اﻷوروﺑﻲ اﻟ ـ ﺠﻨﻮﺑﻲ أن ﻫﺬا اﻟ ﻮﻛﺐ اﻟ ـ ﻠ ﺤﺮ ﺘﻬﻢ اﻟﻐﺎزواﻟﻐ ﺎرﻣﻦ ﻣﺤ ﻄﮫ ﻤﻌﺪ ل ﻳ ﻠﻎ ﺳﺘﺔ ﻣﻠ ﺎراتﻃﻦ ﻓﻲ اﻟﺜﺎﻧ ﺔ وﻫﻮ أﻋﻠﻰﻣﻌﺪّل ﺗﺮا ﻢ ﻳ ﺮﺻﺪ ﻋﻠﻰ اﻹﻃﻼقﻷي ﻮﻛﺐ ﻣﻦ أي ﻧﻮع ﻠﺨّ و ﺺﻫﺬا اﻟﻔ ﺪﻳﻮ ﺗﻔﺎﺻﻴﻞ ﻫﺬا اﻻﻛﺘﺸﺎف .
