The aim of this paper is the
study of the genus 3 curves
from the Arakelov viewpoint. The Jacobian of the curves Cn splits as a product of
elliptic curves, and this fact gives enough arithmetical datum to determine the stable
model and the canonical sheaf of the curves. We use this information to look for
explicit expressions of the modular height and the self-intersection of the dualizing
sheaf of the curves Cn.
