论文摘要
对于特定类型的{\ bf k-}本质标量场，{\ bf k-}本质新兴的重力度量已精确地映射到由Gangopadhyay和Manna建立的Schwarzschild背景的Barriola-Vilenkin（BV）类型度量。基于Chandrasekhar链球菌，我们报告了这种Barriola-Vilenkin型公制的新兴重力场景中存在暗能量的时期大地测量结构的令人兴奋的特征。在存在{\ bf k-}本质的黑暗能量的情况下，我们追踪了类似时间的轨迹，以实现{\ bf k-}本质新兴的barriola-vilenkin时空，这与基本方向相同，但施瓦尔兹柴尔德时空的范围是aphelion和exherelion范围的范围。绘制绑定和未结合的轨道，以达到暗能量密度的固定值。
For a particular type of {\bf k-}essence scalar field, the {\bf k-}essence emergent gravity metric is exactly mapped on to the Barriola-Vilenkin (BV) type metric for Schwarzschild background established by Gangopadhyay and Manna. Based on the S. Chandrasekhar, we report the exciting features of the time-like geodesic structure in the presence of dark energy in an emergent gravity scenario for this Barriola-Vilenkin type metric. We trace the different kinds of trajectories for time-like geodesic in the presence of dark energy for the {\bf k-}essence emergent Barriola-Vilenkin spacetime, which is same as the Schwarzchild spacetime in view of the basic orientation, but the allowed ranges of the aphelion and perihelion distances are much more different. The bound and unbound orbits are plotted for a fixed value of the dark energy density.
