gravitative thickset object like neutron stars and black holes have puzzled scientists and the general world for decades with their utmost sombreness and sometimes counterintuitive nature . And now they might be link up by an even weirder sibling .
In a paper published inPhysical Review Letters , research worker Raúl Carballo - Rubio has propose the theoretic existence of an radical - thick star , where the gravitational collapse is balanced out by several different quantum mechanically skillful issue . Something alike already pass off in neutron stars , where gravity is balanced out by a detestable force-out recognize as degeneracy pressure . But in these new star , the repulsive force play is also grow by the quantum vacuum polarisation .
“ As a moment of the attractive and repulsive force at romp , a massive star can either become a neutron star or wrick into a black hole , ” excuse Carballo - Rubio , from SISSA , in astatement . “ But if the star ’s mass becomes higher than a certain threshold , about 3 time the solar mass , the balance would be broken and the star founder due to the overpowering pull of the gravitational force . ”
The question that Carballo - Rubio wanted to resolve was a ambitious one . Could other quantum mechanics effects fall into dramatic play beyond that mass threshold ? Here move into the quantum vacuum polarization . In this phenomenon , electromagnetic fields make negatron - positron pair , which being matter and antimatter would annihilate back into photon , dissemble as a repulsive violence .
The vacuity polarization would provide an additional military force to balance out the gravitational prostration and could make an fantastically dense hotshot that behaves likewise to a fatal muddle but without an upshot horizon . alike objects have in the past been foretell black stars or gravastars .
“ The novelty in this analysis is that , for the first time , all these ingredients have been assemble together in a fully consistent modelling . Moreover , it has been demo that there exist new stellar configurations , and that these can be described in a surprisingly wide-eyed manner , ” Carballo - Rubio added .
While the theoretic result appears sound , it is ill-defined if such an aim could subsist in our own population . Several gravastar scenario have been disproven because they are not stable , and this resolution might end up being interchangeable to those .
But if they do be , they wo n’t remain hidden for long . Carballo - Rubio believes that by using gravitational observatory likeLIGO and VIRGO , we could mayhap detect them within the next ten .
