Evolution of spatio-kinematic structures in star-forming regions: are Friends of Friends worth knowing?
Evolution of spatio-kinematic structures in star-forming regions: are Friends of Friends worth knowing?
The Friends of Friends algorithm identifies groups of objects with similar spatial and kinematic properties, and has recently been used extensively to quantify the distributions of gas and stars in young star-forming regions. We apply the Friends of Friends algorithm to $N$-body simulations of the dynamical evolution of subvirial (collapsing) …
