Heavy Dark Matter Impact on Massive Stars
Analysis
This paper investigates the interaction between heavy dark matter (DM) and massive stars, focusing on how DM capture evolves throughout stellar evolution. It highlights the importance of accurate stellar modeling, considering factors like composition and halo location, to constrain heavy DM. The study uses simulations and the Eddington inversion method to improve the accuracy of DM velocity distribution modeling. The findings suggest that heavy DM could thermalize, reach equilibrium, or even collapse into a black hole within a star, potentially altering its lifespan.
Key Takeaways
- •The study focuses on the interaction between heavy dark matter and massive stars.
- •Stellar evolution stage, composition, and halo location are crucial for DM capture.
- •Heavy DM could thermalize, reach equilibrium, or collapse into a black hole within a star.
- •Accurate modeling of massive stars is essential for constraining heavy DM.
“Heavy DM would be able to thermalize and achieve capture-annihilation equilibrium within a massive star's lifetime... For non-annihilating DM, it would even be possible for DM to achieve self-gravitation and collapse to a black hole.”
