Star formation — Are complex things understandable?
Star formation is among the most complex processes studied by astronomers to date. It is characterised by a multi-scale interplay between gravity, turbulence, magnetic field, galactic shear as well as ironising radiation. The key to understand star formation is to pin down the physical mechanics at work. I focus on the followings:
- the interaction between galactic disk and molecular cloud, through shear. This mechanism can shut down star formation completely under certainty conditions
- the interaction between turbulence and gravity, which controls cloud fragmentation.
- the interaction between stars and gas, through gravity (molecular contrails). [link]
