We study [Formula: see text]-attractor models with both E-model and T-model potential in an extended Nonminimal Derivative (NMD) inflation where a canonical scalar field and its derivatives are nonminimally coupled to gravity. We calculate the evolution of perturbations during this regime. Then by adopting inflation potentials of the model we show that in the large [Formula: see text] and small [Formula: see text] limit, the value of the scalar spectral index [Formula: see text] and tensor-to-scalar ratio [Formula: see text] are universal. Next, we study reheating after inflation in this formalism. We obtain some constraints on the model’s parameter space by adopting the results with Planck 2018.

非最小暴胀模型中的 α-吸引子和再加热

我们在扩展的非最小导数 (NMD) 暴胀中研究具有 E 模型和 T 模型势的 [公式：见文本]-吸引子模型，其中规范标量场及其导数与重力非最小耦合。我们计算了这一制度下扰动的演变。然后通过采用模型的膨胀势，我们表明在大[公式：见文本]和小[公式：见文本]限制中，标量谱指数[公式：见文本]的值和张量标量比【公式：见正文】是通用的。接下来，我们以这种形式研究通货膨胀后的再加热。通过采用 Planck 2018 的结果，我们获得了对模型参数空间的一些约束。
