We study the dynamics of strongly dissipative Hénon maps at the first bifurcation parameter where the uniform hyperbolicity is destroyed by the formation of tangencies inside the limit set. We prove the existence of an equilibrium measure which minimizes the free energy associated with the non-continuous potential -t logJu, where is in a certain interval of the form (-∞, t0), t0 > 0 and Ju denotes the Jacobian in the unstable direction.
