原星系相互作用中标量场的影响
The influence of scalar fields in protogalactic interactions
摘要：
我们目前的模拟范围内的标量张量理论，在牛顿极限，调查的影响，大量的标量场的两个相等的球形云碰撞的动力学。我们采用SPH代码修改，包括标量场来模拟两个最初的非旋转的原星系接近对方，作为潮汐相互作用的结果，产生的内在角动量。我们已经得到足够大的J/M值，表明内禀角动量可能是潮汐相互作用的结果。
英文摘要：
We present simulations within the framework of scalar-tensor theories, in the Newtonian limit, to investigate the influence of massive scalar fields on the dynamics of the collision of two equal spherical clouds. We employ a SPH code modified to include the scalar field to simulate two initially non-rotating protogalaxies that approach each other, and as a result of the tidal interaction, intrinsic angular momentum is generated. We have obtained sufficient large values of J/M to suggest that intrinsic angular momentum can be the result of tidal interactions.
