Magnetic cycles of HR 1099 and LQ Hydrae

Abstract

We present in this paper a 6-yr time series of magnetic (and brightness) surface images of the K1 subgiant of the RS CVn system HR 1099 (V711 Tauri) and of the young K0 dwarf LQ Hydrae, reconstructed (with the help of a dedicated maximum entropy image reconstruction software) from ZeemanDoppler imaging observations collected at the Anglo-Australian Telescope.
