The objectives of the work presented in this proposal are to describe the dynamical interaction between the star and gas dynamical component surrounding single and binary black holes in galaxy cores by using of realistic Nbody models. We aim to study the evolution in times of relaxation, covering ’collisional’ nuclei (with short relaxation times) as well as ’collisionles’ nuclei (relaxation times as long as the age of the universe). This will allow us to understand the past, present and possible future evolution of galactic nuclei harbouring SMBHs. NBody techniques will be used to evolve models in non-spherical (triaxial) geometries. The influence of stellar evolution and collisions will be studied.

这项工作的目标是用真实的NBody模型描述星系核心中单黑洞和双星黑洞周围的恒星和气体动力分量之间的动力学相互作用。我们的目标是研究弛豫时间的演化，包括‘碰撞’核(具有较短的驰豫时间)以及‘碰撞’核(驰豫时间与宇宙年龄一样长)。这将使我们能够了解蕴藏着SMBH的星系核的过去、现在和未来可能的演化。NBody技术将用于在非球形(三轴)几何图形中进化模型。我们将研究恒星演化和碰撞的影响。
