Left: Doppler tomogram of the Hα line revealing > 3σ (red) emission associated with the orbital phase of the M dwarf (Roche potential shown by the solid black teardrop shape). The majority of the emission may originate from outside the M dwarf, with a higher observed velocity. Right: Trailed spectra of the Hα emission line shown alongside the M dwarf RV model (black solid line), and the higher velocity component (black dotted line; K ≈ 330 km s⁻¹).
