A study led by Ore Gottlieb from MIT investigates the implications of stars capturing primordial black holes (PBH), theorizing two potential outcomes: explosive destruction or quiet consumption. The findings could enhance our understanding of dark matter and the evolutionary paths of stars that interact with PBHs.
- 01Primordial black holes (PBH) may form from the collapse of subatomic matter in the early Universe and could contribute to dark matter.
- 02When a star captures a PBH, it can either lead to explosive destruction or a quiet terminal phase, depending on the rate of material accretion.
- 03The study introduces a framework for modeling the evolution of stars that capture PBHs, utilizing 3D magnetohydrodynamic simulations.
- 04Observational outcomes differ significantly between the two scenarios: explosive events could resemble gamma-ray bursts, while quiet consumption may produce gravitational waves.
- 05The research outlines the need for further studies on the dynamics of PBH capture and its implications for dark matter.

A recent study titled 'The Life and Death of Stars That Capture Primordial Black Holes' by Ore Gottlieb and colleagues from MIT investigates the fate of stars that engulf primordial black holes (PBH). These hypothetical objects may have formed in the early Universe and could play a role in dark matter. The research reveals that when a star captures a PBH, two distinct outcomes are possible based on the accretion rate of stellar material. If the PBH rapidly accretes material, it can lead to the star's explosive destruction, creating phenomena such as x-ray flashes and potential gamma-ray bursts. Alternatively, if the accretion is slow, the star may survive in a quasi-steady state, leading to a quiet terminal phase. The study emphasizes the importance of understanding the conditions that dictate these outcomes, as they have significant implications for future observations of dark matter and stellar evolution. The authors propose that their findings serve as a roadmap for future research into the dynamics of PBH capture and its effects on stars.
