Top Left: Histogram of stellar velocities in the rest frame of OBP-B1, separated into the stars from OBP-Near and Briceno-1. We make this separation since OBP-Near exhibits more coherent and faster motion than Briceno-1, so this serves as a natural division to test gravitational feedback. Taking the median velocities of both OBP-Near and Briceno-1 reveals a velocity difference of 1.86 km/s. Bottom Left: An estimate of the velocity gained by gravitational acceleration from the nearby gas clouds, ∆v over a period of $dt=10$ Myr, (see Eq. \ref{eq:acc_v}). This calculation explains a velocity difference of 0.63 km/s , which is lower than the observed velocity difference by a factor of 3. Right: Projection of dust density, stellar positions, and velocity vectors on the XY Galactic Cartesian plane. The colors indicate the predicted difference in velocity due to the accumulated gravitational acceleration over 10 Myr from the dust and gas.
