The project aims at developing comprehensive models based on numerical simulations for the early mineralogical and chemical evolution of the material in pre-planetary disks. This includes, on the one hand, modeling of the disk structure and evolution, and of processes of matter transport within the disk, and, on the other hand, the modeling of the chemical and physical alteration processes to which the pristine interstellar matter is subjected until its incorporation into large bodies of a planetary system. The required input data for the mineralogical processes, e. g., annealing, evaporation, and growth processes, will be retrieved by mineralogical experiments in A1. The results will allow to predict the composition of the precursor material from which planetesimals and later planets are formed and to compare this with the observational material from bodies in our Solar System, e.g., cometary and meteoritic material, and with observations of protoplanetary accretion disks.

该项目旨在开发基于数值模拟的综合模型，用于研究前行星盘中材料的早期矿物学和化学演化。一方面，包括对盘结构和演化以及盘内物质传输过程进行建模，另一方面，对原始星际物质所经历的化学和物理变化过程进行建模直到它并入行星系统的大天体。矿物学过程所需的输入数据，例如。例如，退火、蒸发和生长过程，将通过 A1 中的矿物学实验来检索。这些结果将允许预测形成星子和后来行星的前体材料的成分，并将其与太阳系天体的观测材料（例如彗星和陨石材料）以及原行星吸积盘的观测进行比较。
