Neutrons Become Cubes Inside Neutron Stars

Neutrons Become Cubes Inside Neutron Stars - Technology Review
http://www.technologyreview.com/blog...27074/?ref=rss

"Inside atomic nuclei, protons and neutrons fill space with a packing
density of 0.74, meaning that only 26 percent of the volume of the
nucleus in is empty.

Today, Felipe Llanes-Estrada at the Technical University of Munich in
Germany and Gaspar Moreno Navarro at Complutense University in Madrid,
Spain, say neutrons can do even better.

These guys have calculated that under intense pressure, neutrons can
switch from a spherical symmetry to a cubic one. And when that happens,
neutrons pack like cubes into crystals with a packing density that
approaches 100%. "

I'm not sure, but this seems wrong to me. Neutrons in the star are
superfluid and rotate in vorticies. This means they exist as wave
forms, like electrons orbiting a nucleus, orbiting the center of the
vortex, which is empty. I don't see how could be could be considered
a cube or any other shape since the neutrons have no individuality,
though perhaps there is some way it is possible.

Note also that the centers of these vorticies are empty of neutrons,
which in the density of a neutron star is hard to believe but that is
how it works. So there is not 100% packing.

Not a cube in sight.
I can spew any garbage I like, nobody can disprove it. I must be a
physicist.

Strictly it is that neutrons can possibly become cubic deep inside a few
very massive neutron stars near to the 2 Msun upper limit.

The crucial point is that radio astronomers have found a pulsar with an
estimated mass 1.97 Msun that should be heavy enough for this effect to
be relevant. Observational tests of their models predictions are
therefore possible and another line on the dense neutron matter phase
diagram.

You have to wonder what happens to the extra gravitational energy
released when they pack as cubes at 100% instead of 74% - does it all go
into deforming the shape of neutrons or do these heavier stars run
hotter and spin up as they very gradually shrink?

The observational signature will probably be a significantly smaller radius
for a given mass, since the density will be a degree stronger.

This really is just another iteration of the 'what is the equation of state
for a neutron star interior?' saga that has been progressing over the past
80 years.

Even now it is hard to tell because definitive measurements of the radius
(and then moments of inertia) for a neutron star are a bitch to measure.

Well, they aren't talking about all neutron stars, but just the very
most massive neutron stars that are nearly at the edge of the neutron
star/blackhole border which is about 2 solar masses.

It would be interesting to see if such a massive neutron star actually
looks like a cube up close, or if it's just spherical like all other
neutron stars.

I don't think being arranged in flattened patterns would affect their
superfluidity.

Note also that the centers of these vorticies are empty of neutrons,
which in the density of a neutron star is hard to believe but that is
how it works. So there is not 100% packing.

Well, I don't know enough about it to comment one way or another about
whether the centers of these voritices are emply of matter.
