Abstract

We have developed two new algorithms for mapping the surface-density of stars in a cluster, and these algorithms are here applied to the Chamaeleon I star cluster. We have also calculated the mean surface-density of companions Sigma as a function of angular separation theta in Chamaeleon I. Our results are fit by Sigma(theta) ~theta^{-2.1} for theta < 11'' (the binary regime), and Sigma ~theta^{-0.73} for theta > 11'' (the clustering regime) -- in good agreement with the results obtained by Larson and Simon for Taurus, rho Ophiuchus and Orion-Trapezium
