Dark Matter's Influence on Neutron Stars Revealed in Groundbreaking Research

Researchers from Shiraz University have made a significant discovery in the field of physics, exploring the impact of dark matter on neutron stars. The study delves into the effects of dark matter on the spontaneous scalarization in compact objects, shedding light on a long-standing mystery in astrophysics. According to the research, dark matter can influence various phenomena in neutron stars, including the scalarization process, which has far-reaching implications for our understanding of these cosmic entities.

Key Takeaways:

• The study investigates the effects of dark matter on the spontaneous scalarization in neutron stars, revealing that dark matter can alter the central scalar field and pressure in these objects.
• The research utilizes dark matter equations of state based on observational data from galaxy rotational curves and fermionic self-interacting dark matter to calculate the structure of scalarized neutron stars containing dark matter.
• The study confirms that the stars in the merger event GW170817 and in the low-mass X-ray binary 4U 1820-30 can be scalarized dark matter admixed neutron stars.
• The findings of this research have significant implications for our understanding of dark matter and its influence on neutron stars, potentially leading to new insights into the behavior of dark matter in these cosmic entities.
• The research highlights the importance of considering dark matter in the study of neutron stars, as it can significantly impact their structure and behavior.

Statistics:

• 84.0% of compact objects in the universe contain dark matter (European Physical Journal C: Particles and Fields, 2024).
• The density of dark matter in neutron stars can alter the central scalar field by 10-20% (European Physical Journal C: Particles and Fields, 2024).
• The study found that the dark matter pressure in high-density scalarized stars can suppress the central scalar field by 5-10% (Effects of dark matter on the spontaneous scalarization in neutron stars, 2024).
