[74.27] Rotational Periods in the \beta Pictoris Moving Group

In this poster, we measure and report observed rotation periods for a sample of eleven stars from the recently identified \beta Pic Moving Group. We find that our average period of rotation is ~ 4 days, larger than the predicted average period, given by De La Reza & Pinzon (2004) and based on the distribution of vsini values and model-dependent mass-radii estimates.

LEH would like to aknowledge support from the NSF Research Experience for Undergraduates program through grant AST - 0453611.
