The metric and field equations are solved for a general quintessence state parameter, with explicit results provided for the physically relevant case $w_q = -2/3$. We analyze the event-horizon structure and the Kretschmann scalar, verify energy-condition constraints, and derive thermodynamic properties including the Hawking temperature and heat capacity to identify stability regimes. Finally, we investigate the photon cylinder for null geodesics. The solution","authors_text":"Franciele M. da Silva, Leonardo G.
