Classification of Chandra X-ray Sources in Cygnus OB2
Vinay L. Kashyap, Mario G. Guarcello, Nicholas J. Wright +11
We have devised a predominantly Naive Bayes method to classify the optical/IR matches to X-ray sources detected by Chandra in the Cygnus OB2 association into foreground, member, an…
X-ray emission from massive stars in Cyg OB2
G. Rauw, Y. Naze, N. J. Wright +9
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-stars, 54 B-stars and 3 WR-stars are analyzed and fo…
The interstellar medium and the massive stellar content toward the SNR G18.1-0.1 and neighboring HII regions
S. Paron, W. Weidmann, M. E. Ortega +2
We perform a multiwavelength study toward the SNR G18.1-0.1 and nearby several HII regions (infrared dust bubbles N21 and N22, and the HII regions G018.149-00.283 and G18.197-00.18…
A multiwavelength study of the supernova remnant G296.8-0.3
E. Sánchez-Ayaso, J. A. Combi, J. F. Albacete Colombo +3
We report XMM-Newton observations of the Galactic supernova remnant G296.8-0.3, together with complementary radio and infrared data. The spatial and spectral properties of the X-ra…
Deep XMM-Newton observation of the Eta Chamaleontis cluster
J. Lopez-Santiago, J. F. Albacete Colombo, M. A. Lopez-Garcia
The members of the Eta Chamaleontis cluster are in an evolutionary stage in which disks are rapidly evolving. It also presents some peculiarities, such as the large fraction of bin…
XMM-Newton detection of the supernova remnant G304.6+0.1 (Kes 17)
J. A. Combi, J. F. Albacete Colombo, E. Sanchez-Ayaso +6
Aims. We report the first detailed X-ray study of the supernova remnant (SNR) G304.6+0.1, achieved with the XMM-Newton mission. Methods. The powerful imaging capability of XMM-Newt…
An X-ray study of the SNR G344.7-0.1 and the central object CXOU J170357.8-414302
J. A. Combi, J. F. Albacete Colombo, J. Lopez-Santiago +7
Aims. We report results of an X-ray study of the supernova remnant (SNR) G344.7-0.1 and the point-like X-ray source located at the geometrical center of the SNR radio structure. Me…
A systematic cross-search for radio/infrared counterparts of XMM-Newton sources
J. A. Combi, J. F. Albacete Colombo, L. Pellizza +7
We present a catalog of cross-correlated radio, infrared and X-ray sources using a very restrictive selection criteria with an IDL-based code developed by us. The significance of t…
Optical spectroscopy of X-MEGA targets I. CPD -59 2635: A New Double-Lined O type Binary in the Carina Nebula
J. F. Albacete Colombo, N. I. Morrell, V. S. Niemela +1
Optical spectroscopy of CPD -59 2635, one of the O-type stars in the open cluster Trumpler 16 in the Carina Nebula, reveals this star to be a double-lined binary system. We have ob…
Optical spectroscopy of X-Mega targets in the Carina Nebula. II. The massive double-lined O-type binary HD 93205
N. I. Morrell, R. H. Barba, V. S. Niemela +8
A new high-quality set of orbital parameters for the O-type spectroscopic binary HD93205 has been obtained combining echelle and coude CCD observations. The radial velocity orbits…
