Surface magnetism in the pulsating RV Tauri star R Scuti
Surface magnetism in the pulsating RV Tauri star R Scuti
We present the surface magnetic field conditions of the brightest pulsating RV Tauri star, R Sct. Our investigation is based on the longest spectropolarimetric survey ever performed on this variable star. The analysis of high resolution spectra and circular polarization data give sharp information on the dynamics of the atmosphere …
