Millisekundenpulsar im Schleudergang

Die Gammastrahlung eines schnell rotierenden Neutronensterns rüttelt an den Modellen zum Ursprung solcher Objekte

(PresseBox) (Bonn, )
Astronomen haben den ersten Gammapulsar in einem Kugelsternhaufen aufgespürt. Mit einer Distanz von etwa 27000 Lichtjahren hält er außerdem noch den Entfernungsrekord in dieser Objektklasse. Seine hohe Leuchtkraft deutet zudem darauf hin, dass J1823-3021A der jüngste bisher gefundene Millisekundenpulsar ist und sein Magnetfeld um einiges stärker als theoretisch vorhergesagt. So lässt er auf eine neue Population solch extremer Objekte schließen. Die Entdeckung gelang einem internationalen Team um Paulo Freire vom Bonner Max-Planck-Institut für Radioastronomie. Die Forscher hatten Daten des Weltraumteleskops Fermi ausgewertet.

Wenn der Kernbrennstoff im Innern eines massereichen Sterns aufgebraucht ist, kollabiert dieser und setzt dabei soviel Energie adkq, zgso ic tfznotiirz uhhddwthhhgelt cjkuxr ybxyibj tnu gdtoz.
