Asymptotic estimates of large gaps between directions in certain planar quasicrystals

For quasicrystals of cut-and-project type in ${\mathbb{R}}^d$, it was proved by Marklof and Strömbergsson that the limit local statistical properties of the directions to the points in the set are described by certain ${\mathrm{SL}}_d(\mathbb{R})$-invariant point processes. In the present paper we make a detailed study of the tail asymptotics of the limiting gap statistics of the directions, for certain specific classes of planar quasicrystals.
