Diffuse X-ray emission in the Cygnus OB2 association
J. F. Albacete Colombo, J. J. Drake, E. Flaccomio +12
We present a large-scale study of diffuse X-ray emission in the nearby massive stellar association Cygnus OB2 as part of the Chandra Cygnus OB2 Legacy Program. We used 40 Chandra X…
The periodicity of the eta Carinae events
A. Damineli, M. F. Corcoran, D. J. Hillier +14
Extensive spectral observations of eta Carinae over the last cycle, and particularly around the 2003.5 low excitation event, have been obtained. The variability of both narrow and…
A multispectral view of the periodic events in eta Carinae
A. Damineli, D. J. Hillier, M. F. Corcoran +13
A full description of the 5.5-yr low excitation events in Eta Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two co…
X-ray flaring from the young stars in CygnusOB2
J. F. Albacete Colombo, M. Caramazza, E. Flaccomio +2
Aims: We characterize individual and ensemble properties of X-ray flares from stars in the CygOB2 and ONC star-forming regions. Method: We analyzed X-ray lightcurves of 1003 CygOB2…
Unveiling the Cygnus OB2 stellar population with Chandra
J. F. Albacete Colombo, E. Flaccomio, G. Micela +2
The aim of this work is to identify the so far unknown low mass stellar population of the ~2Myr old Cygnus OB2 region, and to investigate the X-ray and near-IR stellar properties o…
Optical Spectroscopy of X-Mega targets in the Carina Nebula - VI. FO 15: a new O-Type double-lined eclipsing binary
V. S. Niemela, N. I. Morrell, E. Fernandez Lajus +3
We report the discovery of a new O-type double-lined spectroscopic binary with a short orbital period of 1.4 days. We find the primary component of this binary, FO 15, to have an a…
