Learning outcomes

The student should be able to:
- understand and conceptualize the highly interdisciplinary context of this field of study;
- explain how the observable parameters of the early protostellar phases of star formation relate to the evolution of the protostar and the protoplanetary disk;
- describe the concept of radioactive and other timing methods and their limitations;
- conceptualize the interplay of planetary, astronomical, geological and biological effects in the formation of an habitable planet;
- explain the importance of isotopic studies and how they relate to various measures in timing, in mapping the conditions of the early solar system, in determining the timing of giant impacts and atmospheric stripping, in evaluating the origin of water on Earth and other parts of the solar system;
- describe the profound effects the detection of exoplanetary systems and very recent NIR instrumentation have brought to the astronomical context of protostellar and planetary systems;
- discuss the importance of the solar system small body study (meteorite, asteroid, comet) studies to the fundamental understanding of the origin of our solar system;
- suggest various observational or laboratory projects to address the issues brought up in the studies of early solar system.
