Abstract

We present results of a set of $N$-body simulations to model the future evolution of the 11 young massive clusters hosted in the central region of the dwarf starburst galaxy Henize 2-10, which contains at its center a massive black hole with a mass $M_{ m BH} simeq 2 imes 10^6$ M$_odot$. Nuclear star clusters are present in a great quantity of galaxies of mass similar to Henize 2-10. Our results citep{ASCD15} show that the orbital decay and merging of the Henize 2-10 clusters will likely lead to the formation of a nuclear star cluster with mass $M_{ m NSC} simeq 4-6 imes 10^6$ M$_odot$ and effective radius $r_{ m NSC} simeq 4.1$ pc. Additionally, we found that this mechanism can lead to the formation of disky structures with global properties similar to those of nuclear stellar disks, which reside in many "middle-weight" galaxies. This work confirms and enlarge recent results citep{ASCDS15} that indicate how nuclear star clusters and super massive black holes are only partially correlated, since the formation process of nuclear star clusters is poorly affected by a black hole of the size of that in Henize 2-10. A new result is that nuclear star clusters and nuclear stellar disks may share the same formation path.
