Strong dust processing in circumstellar discs around 6 RV Tauri stars
Strong dust processing in circumstellar discs around 6 RV Tauri stars
We present extended Spectral Energy Distributions (SEDs) of seven classical RV Tauri stars, using newly obtained submillimetre continuum measurements and Geneva optical photometry supplemented with literature data.The broad-band SEDs show a large IR excess with a black-body slope at long wavelengths in six of the seven stars, R Sct being …
