Resumen:
We present quasi-simultaneous interferometric (VLTI/MIDI) and optical and near-IR spectroscopic (CASLEO/REOSC, VLT/CRIRES, GEMINI/PHOENIX) observations of CPD–52 9243 which allow us to constrain its disk structure and kinematics. VLTI/MIDI observations provide strong support for the presence of a dusty disk-like structure around the star, with an inner angular diameter of 5 mas and an inclination angle of ∼ 50°. The dusty structure surrounds a CO gaseous Keplerian ring with a projected rotation velocity of 33 km s-1. The optical line spectrum, crowded with P Cygni profiles, evidences a strong polar wind.
