翻译后摘要-我们提出的热演化计算结果的对象起源于柯伊伯带和向内转移，该地区的外行星。柯伊伯带天体（KBO）被认为是一个水库的一部分，为海王星轨道内部的区域提供了小型冰体（主要是半人马座和木星家族彗星）的通量。我们研究了三个典型的KBO的内部热演化，为108 yr，并使用模拟的最终状态作为初始条件的演化计算的两个典型的半人马座。根据关键的物理参数，如大小和组成，可以确定KBO的一些演变趋势。半人马座区域的后续演化导致每个建模对象的特定特征（主要是表面和次表面成分）和热演化半人马座的共同特征。
Abstract— We present results of thermal evolution calculations for objects originating in the Kuiper belt and transferring inwards, to the region of the outer planets. Kuiper belt objects (KBOs) are considered to be part of a reservoir that supplies the flux of small icy bodies, mainly Centaurs and Jupiter‐family comets, to regions interior to the orbit of Neptune. We study the internal thermal evolution, for ˜108 yr, of three typical KBOs and use the end state of the simulation as initial conditions for evolutionary calculations of two typical Centaurs. Some evolutionary trends can be identified for the KBOs, depending on key physical parameters, such as size and composition. The subsequent evolution in the Centaur region results in both specific features for each modeled object (mainly surface and sub‐surface composition) and common characteristics of thermally evolved Centaurs.
