Dissipative phenomena in extended-bodies interactions I: Methods Dwarf galaxies of the Local Group and their synthetic CMDs
摘要：
在围绕宿主星系的矮卫星星系的轨道演化过程中发生的耗散现象可能会在恒星形成活动中留下签名，并在星系恒星含量的色星等图中留下签名。我们的目标是对这些复杂的现象进行简单而定性的描述。我们开发了一种分析和数值技术，能够研究冲压压力，开尔文-亥姆霍兹不稳定性，瑞利-泰勒和潮汐力作用于恒星形成过程中的分子云。我们认为它与合成彩色星等图技术。我们开发了一种方法来研究气体消耗过程和恒星形成过程之间存在的联系，在两个扩展体相互作用的背景下，特别注意矮星系的动力学制度。
英文摘要：
Dissipative phenomena occurring during the orbital evolution of a dwarf satellite galaxy around a host galaxy may leave signatures in the star formation activity and signatures in the colour magnitude diagram of the galaxy stellar content. Our goal is to reach a simple and qualitative description of the these complicated phenomena. We develop an analytical and numerical technique able to study ram pressure, Kelvin-Helmholtz instability, Rayleigh-Taylor and tidal forces acting on the star formation processes in molecular clouds. We consider it together with synthetic colour magnitude diagrams techniques. We developed a method to investigate the connections existing between gas consumption processes and star formation processes in the context of the two extended-body interaction with special attention to the dwarf galaxies dynamical regime.
