Dear all,
I'm starting to study neutron star accretion and a lot of physical phoenomena coming from different scales come along and a consistent picture is frankly hard to grasp.
But for now, a real mind boggling question can't exit my mind.
Are Neutron stars, as a whole Quantum, or classical objects?
Being made of so many components their coherence should be more or less destroyed, and to testify this is being described by classical hydrodinamical models, at most making use of general relativity, but the trajectories of the accretion material are described by classical forces.
But yet they seems to undergo textbook example of a quantum manybody system, such as superfluidity and related vortexes and quantal phase transitions.
There are some semiclassical pictures but they seems to me a weird way to avoid the question...
Do you have some insight or reference that sort out the question?
Thanks,
A.
