High and intermediate-resolution spectroscopy of Be stars : An atlas of Hγ, He I 4471 and Mg II 4481 lines

The definition of Be stars (Jaschek et al. 1981) as non-supergiant B stars which at least once have shown some emission in the Balmer lines implies a vast phenomenology whose characteristics, the evolution of their understanding and the questions which still remain open have been widely reviewed in...
