Scientific paper

In this poster, we measure and report observed rotation periods for a sample of eleven stars from the recently identified β 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.
