Betelgeuse's hidden companion is stirring the giant star's atmosphere

بیٹلجوس کا پوشیدہ ساتھی ستارہ دیوہیکل ستارے کی فضا میں ہلچل مچا رہا ہے

बेटेलग्यूज़ का छिपा साथी तारा विशाल तारे के वातावरण में हलचल मचा रहा है

Betelgeuse's hidden companion is stirring the giant star's atmosphere

Key points

اہم نکات

मुख्य बातें

  • New radio observations show that Betelgeuse's faint companion star, named Siwarha, is cutting through the red supergiant's extended atmosphere and leaving a wake behind it, like a boat crossing a lake.
  • Data from the Very Large Array in New Mexico and ALMA in Chile, collected between 2021 and 2026, show the star's atmosphere stretching into an egg shape when the companion is farthest away and rounding out when it passes in front of or behind it.
  • The same study, published in The Astronomical Journal, found Betelgeuse has largely recovered from its famous Great Dimming of 2019 and 2020.
  • نئی ریڈیو مشاہدات سے ظاہر ہوا ہے کہ بیٹلجوس کا مدھم ساتھی ستارہ، جس کا نام سیورہا ہے، سرخ دیوہیکل ستارے کی پھیلی ہوئی فضا سے گزر رہا ہے اور اپنے پیچھے لہر چھوڑ رہا ہے، جیسے جھیل میں کشتی گزرے۔ نیو میکسیکو کے ویری لارج ارے اور چلی کے ایلما سے 2021 سے 2026 کے درمیان جمع کیے گئے ڈیٹا سے معلوم ہوا کہ جب ساتھی ستارہ سب سے دور ہوتا ہے تو ستارے کی فضا انڈے کی شکل اختیار کر لیتی ہے، اور جب وہ سامنے یا پیچھے سے گزرتا ہے تو گول ہو جاتی ہے۔ اسی تحقیق میں، جو فلکیاتی جریدے میں شائع ہوئی، یہ بھی معلوم ہوا کہ بیٹلجوس 2019 اور 2020 کی مشہور عظیم مدھم پڑنے سے بڑی حد تک بحال ہو چکا ہے۔
  • नए रेडियो अवलोकनों से पता चला है कि बेटेलग्यूज़ का धुंधला साथी तारा, जिसका नाम सिवरहा है, लाल महादानव तारे के फैले हुए वातावरण से गुज़र रहा है और अपने पीछे लहर छोड़ रहा है, जैसे झील में नाव गुज़रे। न्यू मैक्सिको के वेरी लार्ज ऐरे और चिली के अल्मा से 2021 से 2026 के बीच जुटाए गए आंकड़ों से पता चला है कि जब साथी तारा सबसे दूर होता है तो तारे का वातावरण अंडे का आकार ले लेता है, और जब वह सामने या पीछे से गुज़रता है तो गोल हो जाता है। एस्ट्रोनॉमिकल जर्नल में प्रकाशित इसी अध्ययन में यह भी पाया गया कि बेटेलग्यूज़ 2019 और 2020 के प्रसिद्ध ग्रेट डिमिंग से काफी हद तक उबर चुका है।
