New star described in a model combining relativity and quantum mechanics

A new kind of star is reported in a study by SISSA postdoctoral researcher Raúl Carballo-Rubio. In a paper recently published in Physical Review Letters, Carballo-Rubio describes a novel mathematical model combining general relativity with the repulsive effect of quantum vacuum polarization. The result is a description of an ultra-compact configuration of stars that scientists previously believed did not exist in equilibrium.
