Constraints on Dark Matter in Neutron Stars from Observations
Analysis
This paper investigates the presence of dark matter within neutron stars, a topic of interest for understanding both dark matter properties and neutron star behavior. It uses nuclear matter models and observational data to constrain the amount of dark matter that can exist within these stars. The strong correlation found between the maximum dark matter mass fraction and the maximum mass of a pure neutron star is a key finding, allowing for probabilistic estimates of dark matter content based on observed neutron star properties. This work is significant because it provides quantitative constraints on dark matter, which can inform future observations and theoretical models.
Key Takeaways
- •The study uses nuclear matter models and observational data to constrain the amount of dark matter in neutron stars.
- •A strong linear correlation was found between the maximum dark matter mass fraction and the maximum mass of a pure neutron star.
- •The maximum dark matter mass is estimated to be 0.150 solar masses (at 68% confidence level).
- •This work provides quantitative constraints on dark matter, which can inform future observations and theoretical models.
“At the 68% confidence level, the maximum dark matter mass is estimated to be 0.150 solar masses, with an uncertainty.”
