Context. The Vela OB2 association is a group of ∼10 Myr stars exhibiting a complex spatial and kinematic substructure. The all… Expand Massive stars can be found in wide (hundreds to thousands AU) binaries with other massive stars. We use $N$-body simulations to… Expand We report on the analysis of the Chandra-ACIS data of O, B and WR stars in the young association Cyg OB2. X-ray spectra of 49 O… Expand Rich in HII regions, giant molecular clouds are natural laboratories to study massive stars and sequential star formation. The… Expand We use mid-infrared images from the Spitzer Space Telescope Cygnus X Legacy Survey to search for stellar bow shocks (BSs), a… Expand We report the detection of three new open cluster candidates located in Cygnus. Two of them are projected near the center of the… Expand We present a theoretical model for the non-thermal radio emission from single hot stars, in terms of synchrotron radiation from… Expand As a first step of a vigorous program to investigate the Wind Momentum - Luminosity Relationship (WLR) of Galactic O-stars by… Expand The morphology and stellar content of the Cygnus OB2 association has been determined using 2MASS infrared observations in the J… Expand The morphology and stellar content of the Cygnus OB2 association has been determined using 2MASS infrared observations in the J… Expand
