分形引力

Fractal Gravitation

T Canavesi

摘要:

考虑到银河系中{ $\approx 10^6$ }星在{重心}附近的GAIA数据,我们估计了银河系中不同区域的分维。然后,我们利用这些分形维数来计算引力势考虑介质作为一个连续的分形。最后,{我们使用引力势来推断}银河系中的圆速度{和调整}旋转曲线。{For为此,我们使用两个数值模型,第一个考虑均匀密度,第二个更现实的凸起和圆盘。在这些模型中,我们都没有考虑到暗物质。我们研究它们的有效性比较它们与银河系的圆周速度数据。

英文摘要:

Considering the GAIA data for {$\approx 10^6$} stars around the {barycenter,} we estimate the fractal dimension for different regions in the Milky Way. Then we use those fractal dimensions to calculate the gravitational potential considering the medium as a continuous fractal. Finally, {we use the gravitational potential to infer} the circular velocity {and adjust} rotation curves in the Milky Way. {For this,} we use two numerical models, the first considering uniform density and a second more realistic of a bulge and a disk. In none of these models we consider dark matter. We study their validity comparing them with circular speed data from the Milky Way.
