Are collapsed nuclei, like are discussed in http://prd.aps.org/abstract/PRD/v4/i6/p1601_1" still thought to be possible?

Interesting. When I googled, I got a google books link that let me look at this book: Neutron stars: Equation of state and structure, P. Haensel, Paweł Haensel, A. Y. Potekhin, D. G. Yakovlev. Apparently Bodmner had two separate types that he hypothesized, one with strangeness and one without. The WP article http://en.wikipedia.org/wiki/Strangelet may be helpful. All attempts to detect or produce strangelets have failed.

A detailed mass measurement of a heavy neutron star has ruled out most exotic types

Neat stuff.

I don't really understand how closely this relates to the "collapsed nuclei" paper, as I can only see the abstract right now, and it is unclear to me what they mean.

What about the kind without strangeness, still possible under current understanding? '71 was ages and revolutions ago in particle physics.
