Effects of turbulence and rotation on protostar formation as a precursor to seed black holes

Understand

Context.

• The seeds of the first supermassive black holes may have resulted from the direct collapse of hot primordial gas in $\gtrsim 10^4$ K haloes, forming a supermassive or quasistar as an intermediate stage.
• Aims.
• We explore the formation of a protostar resulting from the collapse of primordial gas in the presence of a strong Lyman-Werner radiation background.
