Editing Lenticular galaxy (section)

===Bars===
Like spiral galaxies, lenticular galaxies can possess a central bar structure. While the classification system for normal lenticulars depends on dust content, barred lenticular galaxies are classified by the prominence of the central bar. SB0<sub>1</sub> galaxies have the least defined bar structure and are only classified as having slightly enhanced surface brightness along opposite sides of the central bulge. The prominence of the bar increases with index number, thus SB0<sub>3</sub> galaxies, like the [[NGC 1460]] have very well defined bars that can extend through the transition region between the bulge and disk.<ref name=bmbook /> [[NGC 1460]] is actually the galaxy with one of the largest bars seen among lenticular galaxies. Unfortunately, the properties of bars in lenticular galaxies have not been researched in great detail. Understanding these properties, as well as understanding the formation mechanism for bars, would help clarify the formation or evolution history of lenticular galaxies.<ref name=BMReview />
