文摘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:mx■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.
