Ein Magnetar im Herzen der Milchstraße

Radioastronomen nutzen Pulsar mit starkem Magnetfeld zum Studium des superschweren schwarzen Lochs

(PresseBox) (München, )
Im Zentrum unserer Milchstraße haben Astronomen einen Magnetar aufgespürt. Dieser Pulsar besitzt ein extrem starkes Magnetfeld und ermöglicht es, die direkte Umgebung des schwarzen Lochs im Herzen der Galaxis zu studieren. Forscher unter Leitung des Bonner Max-Planck-Instituts für Radioastronomie haben zum ersten Mal die magnetische Feldstärke um die Zentralquelle bestimmt und nachgewiesen, dass sie mit Magnetfeldern gefüttert wird. Diese regulieren zudem den Masseneinstrom in das schwarze Loch und erklären die beobachtete Strahlung dieser Schwerkraftfalle.

Pulsare sind rasch rotierende, extrem dicht gepackte Neutronensterne, die wie kosmische Leuchttürme äußerst präzise Radioblitze abstrahlen. Die rund 20 Kilometer durchmessenden Objekte eignen sich in idealer
