Chemical Homogeneity in the Orion Association: Oxygen Abundances of B Stars
K. Cunha, I. Hubeny, T. Lanz
We present non-LTE oxygen abundances for a sample of B stars in the Orion association. The abundance calculations included non-LTE line formation and used fully blanketed non-LTE m…
Pulsed thermal emission from the accreting pulsar XMMU J054134.7-682550
A. Manousakis, R. Walter, M. Audard +1
Aims. Soft X-ray excesses have been detected in several Be/X-ray binaries and interpreted as the signature of hard X-ray reprocessing in the inner accretion disk. The system XMMU J…
Effective area calibration of the reflection grating spectrometers of XMM-Newton. II. X-ray spectroscopy of DA white dwarfs
J. S. Kaastra, T. Lanz, I. Hubeny +1
White dwarf spectra have been widely used as a calibration source for X-ray and EUV instruments. The in-flight effective area calibration of the reflection grating spectrometers (R…
Analysis of Galactic late-type O dwarfs: more constraints on the weak wind problem
W. L. F. Marcolino, J. -C. Bouret, F. Martins +3
We have investigated the stellar and wind properties of a sample of five late-type O dwarfs in order to address the weak wind problem. A grid of TLUSTY models was used to obtain th…
On the Importance of the Interclump Medium for Superionization: O VI Formation in the Wind of Zeta Pup
J. Zsargo, D. J. Hillier, J. -C. Bouret +3
We have studied superionization and X-ray line formation in the spectra of Zeta Pup using our new stellar atmosphere code (XCMFGEN) that can be used to simultaneously analyze optic…
The VLT-FLAMES survey of massive stars: Surface chemical compositions of B-type stars in the Magellanic Clouds
I. Hunter, P. L. Dufton, S. J. Smartt +6
We present an analysis of high-resolution FLAMES spectra of approximately 50 early B-type stars in three young clusters at different metallicities, NGC6611 in the Galaxy, N11 in th…
