The collapse of dark stars, fueled by the annihilation of dark matter particles, gives birth to quasi-stars — a possible source of the 'little red dots' detected by the [tag:jwst]James Webb[/tag] telescope.

The James Webb telescope has discovered 'little red dots' in the early Universe — compact ultra-bright objects that don't fit the textbooks. Perhaps they are envelopes around supermassive black holes, inflated by dark matter annihilation. A star the size of the Solar System, living not on nuclear fusion but on particles from the hidden sector. This not only explains the mystery but also gives an indirect portrait of dark matter. We are peering into an era where familiar physics gives way to something deeper.

🎯 A supermassive dark star would be the size of Jupiter's orbit, but if it were placed at the Sun's position, its average density would be lower than the density of the air you are breathing right now. It would shine exclusively due to the annihilation of dark matter particles, like a cosmic lamp powered by an invisible grid.

\Gamma_{\rm crit} \simeq \frac{4}{3} + C \frac{GM}{Rc^2}

Γ_crit is the critical adiabatic index below which the star becomes unstable; C is a constant of order 2–3 for an n=3 polytrope.

R_{\rm QS} \simeq \sqrt{\frac{L_{\rm Edd}}{4\pi \sigma T_{\rm eff}^4}}

R_QS is determined by the Eddington luminosity and the effective temperature of the envelope.
