Constraints on massive star formation : Cygnus OB2 was always an association
Wright, Nicholas J.; Parker, Richard J.; Goodwin, Simon P.; Drake, Jeremy J. (2014-02-01)We examine substructure and mass segregation in the massive OB association Cygnus OB2 to better understand its initial conditions. Using a well-understood Chandra X-ray selected sample of young stars, we find that Cyg OB2 ... -
Dynamical evolution of star-forming regions
Parker, Richard J.; Wright, Nicholas J.; Goodwin, Simon P.; Meyer, Michael R. (2014-02-01)We model the dynamical evolution of star-forming regions with a wide range of initial properties. We follow the evolution of the regions' substructure using the Q-parameter, we search for dynamical mass segregation using ...
