Early-type stars in the core of the young open cluster Westerlund2
G. Rauw, J. Manfroid, E. Gosset +5
Aims. The properties of the early-type stars in the core of the Westerlund2 cluster are examined in order to establish a link between the cluster and the very massive Wolf-Rayet bi…
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…
Deep Impact : High Resolution Optical Spectroscopy with the ESO VLT and the Keck 1 telescope
E. Jehin, J. Manfroid, D. Hutsemekers +6
We report on observations of comet 9P/Tempel 1 carried out before, during, and after the NASA DEEP IMPACT event (UT July 4), with the optical spectrometers UVES and HIRES mounted o…
