Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions

Figure 2

Slices through the perturbed star along the plane parallel to the perturber star’s trajectory. The first column ((a) and (c)) correspond to encounters with 𝛾=1.2, and the second column ((b) and (d)) correspond to 𝛾=1.6. The first row ((a) and (b)) have 𝑛=3, and the second row ((c) and (d)) have 𝑛=1.5. The contours are the kick velocity within the star due to the encounter normalized to the escape velocity (as a function of 𝑟̃). The outline of the grey region underneath has Δ𝑣/̃𝑣̃^pdesc(𝑟)̃=1, so that the grey region represents the location of where mass is still left after the event.
