Discovery of Raman-scattered C II Lines in V366 Carinae with GHOST/Gemini South.

HEO J.-E. and JEONG M.

Abstract (from CDS):

We report the detection of Raman-scattered C II lines at 7023 and 7054 Å in the symbiotic star V366 Carinae using Gemini High-resolution Optical SpecTrograph (GHOST) at Gemini South. These faint features, originating from the C II doublet at λλ1036 and 1037, 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.
