abstract
We consider two classes of non-toric log del Pezzo $\mathbb{C}^*$-surfaces: on the one side the 1/3-log canonical ones and on the other side those of Picard number one and Gorenstein index at most 65. In each of the two classes we figure out the surfaces admitting a K\"ahler-Einstein metric, a K\"ahler-Ricci soliton and those allowing a Sasaki-Einstein metric on the link of their anticanonical cone. We encounter examples that admit a K\"{a}hler-Ricci soliton but no Sasaki-Einstein cone link metric.

From K\"ahler Ricci solitons to Calabi-Yau K\"ahler cones
If a smooth Fano manifold admits a Kähler-Ricci soliton, then for all sufficiently large k the canonical cone of X times complex projective k-space has a Calabi-Yau cone structure.
