HD 152384: A 5 Myr old debris disk system showing a gaseous ring of refractory elements at the dust sublimation radius
Context: Circumstellar gas around young stars provides key insights into planet formation and disk evolution. HD 152384, a young (5 Myr) A0 V star in Sco-Cen, shows hybrid-disk traits: a modest infrared excess from small dust grains and atomic emission lines dominated by refractory elements, but its
