Morphology and star formation in nearby low surface brightness galaxies.
AULD R., DE BLOK W.J.G., BELL E. and DAVIES J.I.
Abstract (from CDS):
The results have been used to test two ideas describing their star formation: one in which star formation depends solely on the HI gas surface density, and one that depends on differential rotation. We find that a critical HI surface density criterion in the range 2.6-12.6x1020/cm2 (2.1-10.1M☉/pc2) best describes the star-forming ability of these galaxies on local and global scales. A critical gas surface density based on the rotation of the gas is also able to describe the results on a global scale for two of the three galaxies for which we were able to derive rotation curves.
