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.

该项目旨在基于数值模拟来开发全面的模型，以在星际前磁盘中材料的早期矿物学和化学演化。一方面，这包括对磁盘结构和进化的建模，以及磁盘内物质传输过程的建模，另一方面，将原始星际物质的化学和物理变化过程建模，直到将其掺入大型行星系统中。矿物学过程所需的输入数据e。 g。将通过A1中的矿物学实验检索退火，蒸发和生长过程。结果将允许预测形成行星和后来的行星的前体材料的组成，并将其与太阳系中的物体（例如彗星和陨石材料）中的物体进行比较，并观察到了原势型积聚磁盘。
