Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions
Figure 8
(a) The differential collision rate per logarithmic Galactic radius per impact parameter as a function of Galactic radius for several different impact parameters. The solid (dashed) lines were calculated ignoring (including) gravitational focusing. The curves were made by made by integrating (16) (with and without the gravitational focusing term) assuming Salpeter values. (b) The cumulative differential collision rate (integrated over ) per impact parameter with and without gravitational focusing for the same impact parameter values. (a), (b) The vertical line in each panel is placed at pc, the upper bound in our integration across as performed in Section 5.
