A plasma made out of strange-quark matter ( SQM ) and electrons , has a rather high plasma frequency ( \sim 20 MeV ) . Thus , a compact star made of such material all the way up to its surface , i.e. , a bare strange star , would be unable to radiate away its thermal emission . We use the MIT-bag model and assume that SQM is the ground state of nuclear matter at high density . We investigate whether the presence of a magnetic field will allow propagation of radiation at frequencies below the SQM plasma frequencies . Hence , we study the presence of gyrofrequencies in a SQM plasma permeated by a strong magnetic field ( B > 10 ^ { 12 } G ) . We find that small regions in the frequency spectrum allow radiation propagation due to the presence of the magnetic fields . It is likely that narrow bands of radiation would likely be observable from magnetized bare strange stars .
