Dynamical Stability and Environmental Influences in Low Surface Brightness Disk Galaxies
ASTROPHYSICAL JOURNAL, no. 2 (1997): L79-&
摘要
Using analytic stability criteria we demonstrate that, because of their low surface mass density and large dark matter content, low surface brightness (LSB) disks are quite stable against the growth of global nonaxisymmetric modes such as bars. However, depending on their (poorly constrained) stellar velocity dispersions, they may be only...更多
