There is a long standing issue with Gravistars, recent paper here://<![CDATA[ aax_getad_mpb({ "slot_uuid":"f485bc30-20f5-4c34-b261-5f2d6f6142cb" }); //]]>

gives a good overview, and has links therein.

One can understand that the 'Gravitational Vacuum Star', above has evolved from a certain paramiters contained in the above paper, for instance ordinary Stellar Stars, have their own intertwined/embedded processes, a [fusion-core] embedded within a [fission-outer shell[fusion-core]fission-outer shell] nuclear structure.

The paper details 'gravistar signals' to be of a certain type.

In this paper:http://arxiv.org/abs/gr-qc/0509090

they have extended also has a 'chosen' type of perturbations (waves).

Can both have an underlaying common 'co-incedence' factor?

And thus yet another interesting paper:http://arxiv.org/abs/gr-qc/0509088

shows an analytical model of a radiating star undergoing gravitational collapse with non-vanishing shear, interesting papers.
