علماء الفلك لا يستبعدون ولادة كوكب من نجم ميت

ملخص الخبر

اكتشف علماء الفلك كوكبا مرشحا للولادة من بقايا نجم ميت يسمى القزم الأبيض.
كشف التحليل الكيميائي عن وجود نسبة مرتفعة من النيوبيوم في الغلاف الجوي لهذا الجرم.
تشير المواد الثقيلة المكتشفة إلى احتمال تشكل كوكب من الجيل الثاني بعد مراحل تطور النجم.
قد يكون الكوكب قد اكتسب غلافاً جوياً جديداً من مواد قذفها النجم أو كان موجوداً مسبقاً.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

اكتشف علماء الفلك دلائل على وجود كوكب ربما تكون من مواد قذفها نجم قبل تحوله إلى قزم أبيض. وإذا تأكدت هذه الفرضية، فسيكون أول مثال معروف لكوكب من الجيل الثاني يدور حول بقايا نجم.
