Spatially resolved spectroscopy across stellar surfaces: III. photospheric Fe I lines across HD189733A (K1 V)

Show other versions (1)

Spectroscopy across spatially resolved stellar surfaces reveals spectral line profiles free from rotational broadening, whose gradual changes from disk center toward the stellar limb reflect an atmospheric fine structure that is possible to model by 3-D hydrodynamics. Previous studies of photospheri...
