Neue #Goldquelle in alten Daten entdeckt.
Ein Ausbruch eines #Magnetars, aufgezeichnet vor 20 Jahren, beinhaltete ein Signal, das nun als #Nukleosynthese verstanden wird. Dabei entstehen schwere Elemente wie #Gold und #Platin.
Ein Forschungsteam aus den USA konnte den r-Prozess, der bereits vor 70 Jahren zumindest theoretisiert wurde, in einem aufgezeichneten Ausbruch eines Magnetars nachweisen.

A research team has used the Effelsberg and Jodrell Bank radio telescopes to observe the precessing magnetar XTE J1810-197 — a highly magnetised and ultra-dense neutron star — shortly after its X-ray enhanced activity and radio reactivation. This precession damped on a timescale of a few months, which challenges some models used to explain the origin of the mysterious repeating fast radio bursts.

[#ScienceNews @IRAP] Some dying stars emit intense flashes of #radio waves.
One of these #magnetars was spotted in our Milky Way and observed by @nasa 's #NICER and #NuSTAR telescopes. It appeared that the emission of radio waves was accompanied by sudden variations in the magnetar's #rotation velocity. This led to the formulation of hypotheses concerning its internal structure and composition ...

[#ActuScience @IRAP] Certaines étoiles en fin de vie émettent d'intenses flashs d'ondes #radio.
L'un de ces #magnétars a été repéré dans notre Voie Lactée puis observé par les télescopes #NICER et #NuSTAR de la @nasa. Il est ainsi apparu que l'émission d'ondes radio s'est accompagnée de brusques variations de vitesse de #rotation du magnétar. S'est ensuivie la formulation d'hypothèses concernant sa structure interne et sa composition ...
