... Several studies have tried to understand the lack of star formation in LSB galaxies. In general the presence of copious amounts of neutral hydrogen gas in galaxies indicates that they have the capacity to form stars through cloud collapse and star formation. But although LSB galaxies are gas-rich, t ...
