| contents | We report the detection of Raman-scattered C II lines at 7023 and 7054Å in the symbiotic star V366 Carinae using GHOST at Gemini South. These faint features, originating from the C II doublet at $λλ$ 1036 and 1037Å, are rare and have been detected in only two other symbiotic stars: V1016 Cygni and RR Telescopii. Our findings showcase the exceptional sensitivity of GHOST to detect subtle spectral features and open the door to comparative studies of Raman-scattered C II features across these systems. |
