Multi-spectral analysis of chemically peculiar red giant stars (barium stars, S stars, symbiotic stars, metal-deficient carbon
stars), determination of their evolutionary status. Studies of circumstellar environments (CO envelopes, dust, mass loss).
Photometric monitoring of possible eclipsing, ellipsoidal or symbiotic binaries. Long term monitoring of radial velocities aiming at
deriving their orbital elements. Spectroscopic determinations of chemical abundances
