This article explores the distribution and impact of bosonic dark matter (DM) in neutron stars (NSs). The study considers asymmetric self-interacting bosonic DM, which can exist as a dense core or an extended halo around NSs. The presence of DM significantly alters the maximum mass, radius, and tidal deformability of NSs, depending on the boson mass $ m_{\chi} $, self-coupling constant $ \lambda $, and DM fraction $ F_{\chi} $. The research uses the DD2 nuclear matter equation of state (EoS) to model NS matter and shows that incorporating DM into NSs can make their observable parameters consistent with recent multi-messenger observations. For $ m_{\chi} \gtrsim 200 $ MeV and $ \lambda \lesssim 2\pi $, DM-admixed NSs with $ 4\% \lesssim F_{\chi} \lesssim 20\% $ are consistent with the maximum mass and tidal deformability constraints. The study also examines how DM distributions affect NS properties, such as tidal deformability, and how varying DM fractions and coupling constants influence these features. The results indicate that DM can modify the observable characteristics of NSs, providing insights into the potential existence of DM in NSs and its impact on measurable parameters. The research highlights the importance of considering DM in NS models to better understand their properties and the role of DM in astrophysical observations.This article explores the distribution and impact of bosonic dark matter (DM) in neutron stars (NSs).
