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 ...

"A newly discovered star may give us clues to magnetars, how they work"
https://phys.org/news/2023-08-star-clues-mysterious-magnetars.html
"A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays."
I'm ofc still on record for having said I want to be a neutron star when I grow up.

EarthSky | Magnetar slowed down by a volcano-like eruption?

Oh yeah, cool little thing I read about #magnetars :
Up close, the magnetic field is strong enough to polarize the vacuum- as in, tear hard enough at space to create a virtual particle/anti-particle pair. Apparently this causes birefringence, ie refracting the light of the star depending on the direction you look at it.
Which is doubly fun, because the gravitational lensing is also strong enough that you can see the backside of the star from any vantage point. -

A new interesting paper on Magnetars ...
Polarised light, captured by the new IXPE space observatory has indicated that this particular object might have a solid surface, with no atmosphere and only an electromagnetic field surrounding it.
https://www.science.org/doi/10.1126/science.add0080
Reminds me of a recent paper in which three bright hot spots were said to 'migrate' on the surface of another magnetar, which could have been a result of crustal tectonics (!!!) or twisted magnetic field lines creating dynamic hotspots.

Magnetars are def. weirdos.
