CPD-41deg7742: an unusual wind interaction
H. Sana, E. Gosset, G. Rauw +4
We summarize the results of a multiwavelength observing campaign on the massive eclipsing binary CPD-41deg7742, another remarkable object in the young open cluster NGC 6231. Our ca…
The massive binary CPD-41degr7742 II. Optical light curve and X-ray observations
H. Sana, E. Antokhina, P. Royer +4
In the first paper of this series, we presented a detailed high-resolution spectroscopic study of CPD - 41degr7742, deriving for the first time an orbital solution for both compone…
Isotopic abundances of carbon and nitrogen in Jupiter-family and Oort Cloud comets
D. Hutsemekers, J. Manfroid, E. Jehin +5
The 12C14N/12C15N and 12C14N/13C14N isotopic ratios are determined for the first time in a Jupiter-family comet, 88P/1981 Q1 Howell, and in the chemically peculiar Oort Cloud comet…
Photometric monitoring of the doubly imaged quasar UM673: possible evidence for chromatic microlensing
Th. Nakos, F. Courbin, J. Poels +12
We present the results of two-band CCD photometric monitoring of the gravitationally lensed quasar Q 0142-100 (UM 673).The data, obtained at ESO-La Silla with the 1.54 m Danish tel…
Isotopic abundance of nitrogen and carbon in distant comets
J. Manfroid, E. Jehin, D. Hutsemekers +5
The 12C14N/12C15N and 12C14N/13C14N isotopic ratios have been determined in comets C/1995 O1 (Hale-Bopp), C/2001 Q4 (NEAT) and C/2003 K4 (LINEAR) at heliocentric distances of, resp…
