The Dynamic Infrared Sky: A Perspective of Planet Formation

The last decade has seen revolutionary discoveries of thousands of exoplanets in hundreds of multi-planet systems. It becomes clear that large planets very close to their central stars are surprisingly common. Their presence is incompatible with, and brings serious challenges to old wisdom of planet formation. Nonetheless, the solar system remains our best understood planetary system and the basis of most planet formation models. Therefore, it is of critical importance to place the solar system in proper context to better understand planet formation in general. I will discuss recent progress in using the time domain to explore various stages of extrasolar planet formation that correspond to key signposts in the history of the solar system, and the implications of the results in broader context. SOFIA, with its capability in both time and wavelength domains, can provide exciting and deeper insight to how planets come to be.
