It has been shown that, if these objects are compact enough to exhibit the presence of the light-ring required to mimic the phenomenology of general relativity black holes, they must have at least one additional light-ring. The stability of the inner light ring has been proven under the assumption of Einstein equations and the validity of the null energy condition.
