Diffuse inter-filament gas is likely a key fuel source for massive star formation

Researchers from Kyushu University have discovered that diffuse gas surrounding dense filaments in a nearby stellar nursery plays a much larger role in star formation than previously recognized. By tracking the movement of gas in the Monoceros R2 hub–filament system, the team found that low-density gas contributes to hub growth both through direct inflow and by replenishing nearby dense filaments. Their findings show that overlooking this diffuse gas could substantially underestimate the amount of material available to build massive stars.
