  This is the second of a series of papers dealing with an analog in Arakelov
geometry of the holomorphic Lefschetz fixed point formula. We use the main
result of the first paper to prove a residue formula "`a la Bott" for
arithmetic characteristic classes living on arithmetic varieties acted upon by
a diagonalisable torus; recent results of Bismut-Goette on the equivariant
(Ray-Singer) analytic torsion play a key role in the proof.
