This paper is devoted to observe the physical attributes of static spherically symmetric isotropic compact stellar candidates in the context of Rastall theory of gravity. In order to inspect the structural composition of compact objects, the Heintzmann ansatz is taken into account. The unknown parameters associated with Heintzmann ansatz are evaluated through matching conditions with derived values of radii and masses of some specific star models. The consistency of the adopted ansatz is analyzed via graphical interpretation of matter variables, equation of state parameter, mass components, energy constraints, causality condition, stellar equation and adiabatic index for several choices of Rastall parameter. It is observed that the stars under consideration manifest stable structures corresponding to Heintzmann ansatz in this framework. Moreover, it is shown that for vanishing Rastall coupling parameter, the standard outcomes of general relativity can be retrieved.

本文致力于在拉斯托引力理论的背景下观察静态球对称各向同性致密恒星候选者的物理属性。为了检查致密物体的结构组成，需要考虑海因茨曼模拟。与 Heintzmann ansatz 相关的未知参数通过将条件与某些特定恒星模型的半径和质量的导出值进行匹配来评估。通过对物质变量、状态参数方程、质量分量、能量约束、因果条件、恒星方程和绝热指数的图形解释，对拉斯托参数的几种选择，分析了所采用的拟像的一致性。据观察，所考虑的恒星表现出与该框架中的海因茨曼拟像相对应的稳定结构。此外，结果表明，对于消失的拉斯托尔耦合参数，可以恢复广义相对论的标准结果。
