Abstract

We present here two examples of the use of interferometric observations to study stellar rotation effects (flattening and gravity darkening) and spots on the stellar photospheres. From the fit of simple geometrical models to two sets of VLTI data (VINCI and AMBER) using the LITpro tool from JMMC we can estimate stellar physical parameters and have insights on the photospheric intensity distribution.
