Aims. The X-ray emission of massive stars has been studied when these objects are in their main-sequence phase, as well as when they are in their Wolf-Rayet phase. However, the X-ray properties of the transitional luminous blue variable (LBV) phase remain unknown. Methods. Using a dedicated but limited XMM-Newton survey and archival XMM-Newton and Chandra observations, we performed the first X-ray survey of LBVs: about half of the known LBVs or candidate LBVs were studied. Results. Apart from… 

Figures and Tables from this paper


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 for the brighter

Luminous blue variables: An imaging perspective on their binarity and near environment

Luminous blue variables (LBVs) are rare massive stars with very high luminosity. They are characterized by strong photo-metric and spectroscopic variability related to transient eruptions. The

Wind collisions in three massive stars of Cygnus OB2

Aims. We wish to study the origin of the X-ray emission of three massive stars in the Cyg OB2 association: Cyg OB2 #5, Cyg OB2 #8A, and Cyg OB2 #12. Methods. To this aim, dedicated X-ray observations

Study of the luminous blue variable star candidate G26.47+0.02 and its environment

Aims. The luminous blue variable (LBV) stars are peculiar very massive stars. The study of these stellar objects and their surroundings is important for understanding the evolution of massive stars

On the Binary Nature of Massive Blue Hypergiants: High-resolution X-Ray Spectroscopy Suggests That Cyg OB2 12 is a Colliding Wind Binary

The blue hypergiant Cyg OB2 12 (B3Ia+) is a representative member of the class of very massive stars in a poorly understood evolutionary stage. We obtained its high-resolution X-ray spectrum using

Tracing back the evolution of the candidate LBV HD 168625

Context. The luminous blue variable phase is a crucial transitory phase that is not clearly understood in the massive star evolution. Aims. We have obtained far-infrared Herschel /PACS imaging and

Luminous Blue Variables

Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state and what they are connected

Progenitor constraints for core-collapse supernovae from Chandra X-ray observations

The progenitors of hydrogen-poor core-collapse supernovae (SNe) of types Ib, Ic and IIb are believed to have shed their outer hydrogen envelopes either by extremely strong stellar winds,

Six Faint Gamma-ray Pulsars Seen with the Fermi Large Area Telescope -- Towards a Sample Blending into the Background

Context: GeV gamma-ray pulsations from over 140 pulsars have been characterized using the Fermi Large Area Telescope, enabling improved understanding of the emission regions within the neutron star




The key empirical property of the X-ray emission from O stars is a strong correlation between the bolometric and X-ray luminosities. In the framework of the Chandra Carina Complex Project, 129 O and

An X-Ray Investigation of the NGC 346 Field in the Small Magellanic Cloud. III. XMM-Newton Data
