We study the dynamics of two three-level atoms interacting with independent bosonic Lorentzian reservoirs at zero temperature. Such systems can be created in far astronomical objects. Quantum mechanical behaviour of these particles can produce detectable effects on the spectroscopic identifications of these objects, if such behaviour remain stable during the interaction with their media. It is shown that de-tuning increases the robustness of negativity and geometric discord as the measures of entanglement and quantum correlation beyond entanglement, respectively against interaction with reservoirs. In separable and bound entangled regions, negativity is zero while the geometric discord remains not zero. We also study the evolution of geometric discord and negativity for an isotropic state.
