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

Understand

We study the structural properties like the gravitational mass, radius and tidal deformability of dark matter (DM) admixed strange quark stars (SQSs).

• For the purpose we consider the vector MIT Bag model to describe the strange quark matter (SQM) and investigate the possible presence of accreted DM in the SQSs consequently forming DM admixed SQSs.
• We introduce feeble interaction between SQM and the accreted fermionic DM via a vector dark boson mediator.
• Considering the present literature, in the context of possible presence of DM in SQSs, this work is the first to consider interaction between DM and SQM in the DM admixed SQSs.
