Representative rest-frame spectra for each of the five TDEs in our sample (AT 2018hyz, AT 2018zr, AT 2020nov, AT 2020zso, and PTF09djl) showing broad, double-peaked Hα emission consistent with disk-like kinematics. Each panel displays a single epoch selected to highlight the double-peaked structure, with the offset from peak optical brightness shown in the top-left corner. The diversity in peak separation, asymmetry, and profile shape reflects underlying differences in disk geometry, orientation, and emission structure, which we explore in detail through elliptical-disk modeling in Section 5.3.
