| contents | We show that the compact star XTE J1814-338 can be explained as a strange star admixed with self-interacting bosonic dark matter (BDM), provided the dark matter fraction exceeds approximately 70\%. This interpretation leads to a robust constraint on the BDM particle mass: $m_χ\lesssim 307(λ/π)^{1/4}$ MeV ($λ$ is the dimensionless coupling constant of the BDM). The result is independent of formation scenario and microphysical details and is falsifiable by future NICER and LIGO/Virgo observations. |
