The Tai Chi in Star Formation

Presenter: Hua-bai Li (CUHK)

Tai Chi, a Chinese martial art developed based on the laws of nature, emphasises how 'to conquer the unyielding with the yielding'. The recent observation of star formation shows that gravity, turbulence and magnetic fields may all play a role in star formation. Their detailed interaction, however, is always a topic of controversy due to the difficulties in both observations and simulations, especially when magnetic fields are involved. Is cloud turbulence super- or sub-Alfvenic? Are molecular cloud mass super- or sub-critical? I will review our recent quest of the answers of these central questions in star formation. And how Tai Chi may give us some inspiration.
