We propose a research program that is driven by basic questions concerning our origins: How do planets form? How is the Solar System a typical planetary system and how is it different? What does the makeup of meteorites tell us about the formation environment of the Solar System's planets? What types of events are critical for creating diversity among the thousand planetary systems now known? How does the star formation process itself and the early evolution of circumstellar discs affect the formation of planets? What does debris (asteroids, comets, and dust) tell us about planet building? Using a combination of observations and supercomputing, we will addresses these questions and explore links between the many stages of planet formation. Our investigations will cover a broad range of evolutionary epochs of planetary systems, from the formation and early evolution of circumstellar discs to the long-term orbital configurations of planets and their debris. Such a scope includes processes that range from setting the initial conditions for planet formation to determining what is typically observed. World-class observing facilities, such as the Atacama Large Millimeter/submillimeter Array, will be used to reveal the structures of discs. High-performance computing will be used to tackle simulations of planetary orbital dynamics, planet-forming disc evolution, and the processing of solids found in meteorites. The research we propose in this NSERC grant aims to test some of the basic hypotheses among planet-formation paradigms.**** **

我们提出了一个研究计划，是由有关我们的起源基本问题驱动：行星是如何形成的？太阳系是一个典型的行星系统，它有什么不同？陨石的组成告诉我们太阳系行星的形成环境是什么？什么类型的事件对于在现在已知的上千个行星系统中创造多样性至关重要？星星形成过程本身和星周盘的早期演化是如何影响行星形成的？碎片（小行星，彗星和尘埃）告诉我们关于行星的建造的什么？通过结合观测和超级计算，我们将解决这些问题，并探索行星形成的许多阶段之间的联系。我们的调查将涵盖广泛的行星系统的演化时代，从形成和早期的行星盘的长期轨道配置和碎片的星周盘的演变。这样的范围包括从设定行星形成的初始条件到确定通常观察到的过程。世界级的观测设施，如阿塔卡马大型毫米/亚毫米阵列，将用于揭示光盘的结构。高性能计算将用于模拟行星轨道动力学、行星形成盘演化以及陨石中发现的固体处理。我们在NSERC资助下提出的研究旨在测试行星形成范式中的一些基本假设。 **
