Abstract
We have initiated an observational program to investigate evolved stars from high spatial and spectral resolution observations with GI2T (Grand Interferometre a 2 Telescopes) in the visible and near-infrared wavelengths. The scientific objectives are: measuring limb darkening, resolving small- scale structures and understanding stellar pulsation. The target selection and model fitting procedure are discussed here. Also presented are the limiting magnitude of GI2T/REGAIN for our program and simulated visibility curves. Actual observations are planned during coming months.
