Vector dark boson mediated feeble interaction between fermionic dark matter and strange quark matter in quark stars

We study the structural properties like gravitational mass, radius and tidal deformability of dark matter (DM) admixed strange quark stars (SQSs). For purpose we consider vector MIT Bag model to describe (SQM) investigate possible presence accreted DM in SQSs consequently forming SQSs. introduce feeble interaction between SQM fermionic via a boson mediator. Considering present literature, context SQSs, this work is first The mass fermion ($m_{\chi}$) mediator ($m_{\xi}$) coupling ($y_{\xi}$) them are determined accordance with constraint from Bullet cluster day relic abundance, respectively. find that reduces both star compared no-DM case. massive fermion, lower values maximum chosen $m_{\chi}$ corresponding $m_{\xi}$ $y_{\xi}$, computed satisfy all various astrophysical constraints.We obtain configurations consistent GW190814 observational data. Hence secondary compact object associated event may be SQS.
