Inflationary attractors from nonminimal coupling

We show explicitly how the E model attractor is obtained from the general scalar-tensor theory of gravity with arbitrary conformal factors in the strong coupling limit. By using conformal transformations, any attractor with the observables ns and r can be obtained. The existence of attractors imposes a challenge to distinguish different models.
