##### Abstract

For an arbitrary compact Lie group $G$, we describe a model for rational $G$–spectra with toral geometric isotropy and show that there is a convergent Adams spectral sequence based on it. The contribution from geometric isotropy at a subgroup $K$ of the maximal torus of $G$ is captured by a module over ${H}^{\ast }\left(B{W}_{G}^{e}\left(K\right)\right)$ with an action of ${\pi }_{0}\left({W}_{G}\left(K\right)\right)$, where ${W}_{G}^{e}\left(K\right)$ is the identity component of ${W}_{G}\left(K\right)={N}_{G}\left(K\right)∕K$.
