Plasmoid collapse at another Supernova
This is a sequel to the post (about an hour ago) about the Crab Nebula and its plasmoid.
E0102, located in the SMC, is also claimed to be a supernova remnant. There are similarities in the two observations.
excerpt from Chandra:
Chandra observations of E0102 show that the supernova remnant is dominated by a large ring-shaped structure in X-rays, associated with the blast wave of the supernova. The new MUSE data revealed a smaller ring of gas that is expanding more slowly than the blast wave. At the center of this ring is a point-like source of X-rays. Together, the small ring and point source act like a celestial bull's eye.
The combined Chandra and MUSE data suggest that this source is an isolated neutron star, created in the supernova explosion about two millennia ago. The X-ray energy signature, or "spectrum," of this source is very similar to that of the neutron stars located at the center of two other famous oxygen-rich supernova remnants: Cassiopeia A (Cas A) and Puppis A. These two neutron stars also do not have companion stars.
The linked page offers views in different wavelengths.
The image in X-ray is important. X-rays are the result of high energy synchrotron radiation so a very strong electrical current is required to achieve the energy in X-rays.
In EU, every neutron star is a plasmoid. A neutron star is impossible, a hypothesis never tested.
In E0102, the entire outer ring is active in X-ray. E0102 also has prominent filament spokes between the plasmoid at the center and the outer ring indicating an electrical connection.
Oxygen-rich supernova remnants like E0102 are important for understanding how massive stars fuse lighter elements into heavier ones before they explode. Seen up to a few thousand years after the original explosion, oxygen-rich remnants contain the debris ejected from the dead star's interior. This debris (visible as a green filamentary structure in the combined image) is observed today hurtling through space after being expelled at millions of miles per hour.
(excerpt break for my comment):
No spectra are provided here but a paper on the Crab Nebula stated the spectra from the filaments provided the velocity values for the M1 motions.
An electrical current within a filament is not like molecules moving in a gas cloud. This extreme velocity is probably not justified.
But how did this neutron star end up in its current position, seemingly offset from the center of the circular shell of X-ray emission produced by the blast wave of the supernova? One possibility is that the supernova explosion did occur near the middle of the remnant, but the neutron star was kicked away from the site in an asymmetric explosion, at a high speed of about two million miles per hour. However, in this scenario, it is difficult to explain why the neutron star is, today, so neatly encircled by the recently discovered ring of gas seen at optical wavelengths.
The assumption is only an explosion caused what is observed.
The lack of symmetry is awkward to explain because the star which exploded with its 'blast wave' should have been a symmetrical sphere.The article describes possible scenarios for the observation but without a conclusion.
An electrical collapse is not required to maintain symmetry with the filamentary structures which emerged from the event.
The oxgen content in the debris is assumed to be a clue about the star's core at the time of the supernova.
The SAFIRE project has confirmed a number of elements are created on the anode's surface. I believe our Sun's surface has most of the periodic table, observed by their absorption lines, suggesting an extreme age.
Any conclusions drawn from the metallicity in the debris about the original starare invalid. It is conceivable the supernova itself could have fused some elements.
Cosmologists have more to learn about a supernova. They are rare. Unfortunately it is impossible to know what was present before this E0102 supernova event which resulted in the observed debris.
