- Title
- Intrisic Properties of the Bars Formed by the Bar Instability in Flat Stellar Disks
- Abstract
- Recent observations have revealed that some properties of galactic bars have been uncovered on a statistically meaningful levels of accuracy using a large sample of galaxies. As a result, it has been found that bars in SB0-SBb galaxies are longer than those in SBc to SBd galaxies. Furthermore, also found are such properties that the longer bars have larger amplitudes, and show more elongated shapes. However, these systematic bar properties have never been explained physically. In this talk, I show the properties of the bars formed by the bar instability for flat stellar disk models which are constructed on the basis of exact equilibrium distribution functions. Then, I demonstrate that the properties of the simulated bars are, in large measure, similar to those of the observed bars, and that the amplitude, length, and axis ratio are strongly correlated to an initial typical Toomre’s Q value. Taking into consideration these results, I discuss what the Hubble sequence represents.
