A multiwavelength investigation of the massive eclipsing binary Cyg OB2 #5
N. Linder, G. Rauw, J. Manfroid +5
The properties of the early-type binary Cyg OB2 #5 have been debated for many years and spectroscopic and photometric investigations yielded conflicting results. We have attempted…
The 16OH/18OH and OD/OH isotope ratios in comet C/2002 T7 (LINEAR)
D. Hutsemekers, J. Manfroid, E. Jehin +2
The 16OH/18OH and OD/OH isotope ratios are measured in the Oort-Cloud comet C/2002 T7 (LINEAR) through ground-based observations of the OH ultraviolet bands at 3063 A (0,0) and 312…
Chandra monitoring of the very massive binary WR20a and the young massive cluster Westerlund2
Yael Naze, Gregor Rauw, Jean Manfroid
Results: The two Wolf-Rayet stars WR20a (WN6ha+WN6ha) and WR20b (WN6ha) were analyzed in detail. They are both very luminous and display very hard spectra, but WR20b does not seem…
The impact and rotational lightcurves of Comet 9P/Tempel 1
Jean Manfroid, Damien Hutsemékers, Emmanuël Jehin +6
UVES and HIRES high-resolution spectra of comet 9P/Tempel 1 are used to investigate the impact and rotational light curves of various species with a view toward building a simple m…
The atypical emission-line star Hen3-209
Y. Naze, G. Rauw, D. Hutsemekers +3
We analyse observations, spanning 15 years, dedicated to the extreme emission-line object Hen3-209. Our photometric data indicate that the luminosity of the star undergoes marked v…
Early-type stars in the young open cluster IC1805. II. The probably single stars HD15570 and HD15629, and the massive binary/triple system HD15558
M. De Becker, G. Rauw, J. Manfroid +1
Aims: We address the issue of the multiplicity of the three brightest early-type stars of the young open cluster IC1805, namely HD15570, HD15629 and HD15558. Methods: For the three…
