         | While you're still able to edit your comment, you might
         | consider something like quoting the relevant part of the
         | article at the top:
         | 
         | "Some stars, though, have much more powerful fields [...]
         | neutron stars have magnetic fields 1 trillion times stronger
         | than the Sun's. As the massive [progenitor] star collapses, its
         | magnetic field lines are packed into a much tighter space, and
         | the field strength increases. But then there are magnetars:
         | These neutron stars have fields 1,000 times stronger [...] and,
         | given that most stars aren't all that magnetic to begin with,
         | those are more difficult to explain."
         | 
         | Or indeed, from the subtitle near the very top:
         | 
         | "and it might explain the origin of highly magnetic cinders
         | known as magnetars"
         | 
         | and then suggest your physics SE link (or rather, the accepted
         | answer) for more information on the magnetic fields of neutron
         | stars -- including theories about their origin as "fossils" of
         | the progenitor star (like, but not quite as magnetic as, the
         | star discussed in the article, which may offer support for the
         | "fossil" theory) and internal dynamics during the collapse into
         | the neutron star, or even after the neutron star has formed.
         | 
         | The accepted answer there
         | <https://physics.stackexchange.com/posts/526296/revisions > is
         | a decent short read that is related to, and expands upon, the
         | paragraph extracted above. However the answer and comments
         | there are now several years old now, and are about an area of
         | active research -- for example, one of the linked academic
         | papers was less than a year old on the date the answer was
         | submitted.
         | 
         | Or, perhaps you (and others) might do something like that next
         | time, to do justice to an interesting and relevant link.
         | 
         | Finally, here is a link to the (open access) PDF of the paper
         | published in Science, courtesy of the European Southern
         | Observatory (and several of the authors' Canadian and European
         | funding agencies): <https://www.eso.org/public/archives/release
         | s/sciencepapers/e...>
