In a Bootes I-like ultrafaint dwarf simulated at 0.95 pc resolution, stellar winds and supernovae expel most newly made metals but retain over 80% of the cold gas, so stellar feedback alone cannot quench these galaxies.

High-resolution three-dimensional simulations of gas removal from ultrafaint dwarf galaxies. I. Stellar feedback
In a Bootes I-like ultrafaint dwarf simulated at 0.95 pc resolution, stellar winds and supernovae expel most newly made metals but retain over 80% of the cold gas, so stellar feedback alone cannot quench these galaxies.
