Seltenes Doppelsternsystem in unserer Galaxie detektiert

(PresseBox) (Innsbruck, )
Erstmals entdeckten Forschende - darunter Astroteilchenphysiker der Universität Innsbruck - ein neues Doppelsternsystem anhand seines spezifischen Gammastrahlen-Signals. Die Beobachtungen wurden mit dem Gammastrahlen-Weltraumteleskop Fermi der NASA durchgeführt. Die beteiligten Wissenschaftler berichten darüber aktuell im Fachmagazin Science.

Olaf und Anita Reimer, beide Astroteilchenphysiker an der Universität Innsbruck, waren an der Entdeckung von 1FGL J1018.6-5856, einem neuen Doppelsternsystem in unserer Milchstraße beteiligt. Unter einem solchen Doppelstern- oder Binärsystem stellt man sich ein aus einem kompakten astronomischen Objekt, beispielsweise einem Neutronenstern oder einem Schwarzen Loch, und einem massereichen Stern bestehendes gemeinsames Sternsystem vor. Unter bestimmten Bedingungen werden in diesem hochenergetische Gammastrahlen produziert.
