| Abstract: |
Recent observations indicate that spiral galaxies harbor massive black holes (BHs) at their centers, whose masses range from ∼ 106 M⊙ to ∼ 109 M⊙ (e.g., Marconi & Hunt 2003). As a dynamical influence of such large-mass BHs, numerical simulations have demonstrated that a bar in a barred galaxy could be dissolved in some circumstances (e.g., Shen & Sellwood 2004; Athanassoula et al. 2005; Hozumi & Hernquist 2005). In previous studies, the minimum BH mass required for bar dissolution and the dissolution mechanism was the main concern. On the other hand, the present work is devoted to the investigation of what type of bar is more easily destroyed for a given mass BH. In order to obtain a wide variety of bars in shape and amplitude, we adopt two kinds of mass profiles with various velocity structures for razor-thin disks. |
