Photoevaporation and close encounters: how the environment around Cygnus OB2 affects the evolution of protoplanetary disks
M. G. Guarcello, J. J. Drake, N. J. Wright +10
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on t…

Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
L. Gkouvelis, J. Fabregat, J. Zorec +5
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotomet…

The statistical uncertainties on X-ray flux and spectral parameters from Chandra ACIS-I observations of faint sources: Application to the Cygnus OB2 Association
J. F. Albacete-Colombo, E. Flaccomio, J. J. Drake +3
We investigate the uncertainties of fitted X-ray model parameters and fluxes for relatively faint Chandra ACIS-I source spectra. Monte-Carlo (MC) simulations are employed to constr…
