Junger Pulsar strahlt im Gammalicht

Wissenschaftler entdecken einen Neutronenstern im Zentrum des nahen Supernova-Überrests CTA 1

(PresseBox) (München, )
Erstmals haben Wissenschaftler einen rotierenden Neutronenstern - einen Pulsar - anhand seiner Gammastrahlung identifiziert. Die Entdeckung gelang einem internationalen Team um Gottfried Kanbach vom Max-Planck-Institut für extraterrestrische Physik in Garching. Für ihre Beobachtungen nutzten die Forscher das Fermi Gamma-Ray Space Telescope. (Science Express, 16. Oktober 2008)

Das Leben von sehr massereichen Sternen endet nach wenigen Millionen Jahren in einer Supernova. Als weithin sichtbare Überreste der Sterne bleiben die abgestoßenen Hüllen als Explosionswolken und die Kerne als Neutronensterne oder schwarze Löcher zurück. In den Gaswolken verteilen sich die aus Fusionsreaktionen im Innern der Sterne erzeugten höheren Elemente im interstellaren Medium.
