7月10日 Observational Planet Formation
2017年07月05日

  报告题目:Observational Planet Formation

  报告人:董若冰教授(加拿大维多利亚大学)

  摘要:Planets form in gaseous protoplanetary disks surrounding newborn stars. As such, the most direct way to learn how they form from observations, is to directly watch them forming in disks. In the past, this was difficult due to a lack of observational capabilities; as such, planet formation was largely a subject of pure theoretical astrophysics. Now, thanks to a fleet of new instruments with unprecedented resolving power that have come online recently, we have just started to unveil features in resolve images of protoplanetary disks, such as gaps and spiral arms, that are most likely associated with embedded (unseen) planets. By comparing observations with theoretical models of planet-disk interactions, the masses and orbits of these still forming planets may be constrained. Such planets help us directly test various planet formation models. This marks the onset of a new field — observational planet formation. I will introduce the current status of the field, and highlight a few latest major advances.
