This paper investigates the dynamics of quantum correlations, specifically entanglement,steering, and Local Quantum Uncertainty (LQU), in a bipartite qubit system coupled to independent,isolated circular spin-star baths. Contrary to intuition, we demonstrate that substantialquantum correlations can persist even in the absence of direct bath-bath interactions. Our findingsreveal that the symmetry of the system and initial atomic populations are critical factorsin facilitating robust steering and strong quantum correlations. We further show that increasingthe internal bath coupling can enhance the quantum correlations between the baths regardless ofindirect interaction. Conversely, increasing the internal bath coupling and bath-qubit couplingcan weaken the quantum correlations between the central qubits. Interestingly, indirect couplingbetween the baths, mediated by the qubits, can lead to robust entanglement and steering. TheLQU provides deeper insights into the interplay between uncertainty and correlation. The initialconditions minimize uncertainty and maximize correlations, while imbalances result in increasedLQU. These results have profound implications for quantum information processing and control,offering potential strategies for optimizing quantum device performance and protocol design.
