The WR content of IC10 - first detection of WC9 stars in a low metallicity environment? (2001)

Royer, P, Smartt, S J, Manfroid, Jean, Vreux, Jean-Marie

We present deep, narrow-band photometry of the Local Group starburst galaxy IC 10. Our dedicated photometric system provides detection of 13 new Wolf-Rayet (WR) stars and allows spectral subtypes to...

A dedicated photometric system for the classification of Wolf-Rayet stars (1998)

Royer, P, Vreux, Jean-Marie, Manfroid, Jean

We present here tests of a five-filter photometric system aimed at WR classification. In addition to the well-known easy separation between the WN and WC spectral types, these tests indicate...

WR22 as a core hydrogen-burning Wolf-Rayet star (1995)

Rauw, Grégor, Vreux, Jean-Marie, Gosset, Eric, Hutsemekers, Damien, Magain, Pierre

The analysis of an extensive sample of high resolution spectra of the Wolf-Rayet binary WR22 recently allowed us to determine a minimum mass of 72 M_solar for the WN7 star. With such a high mass,...

HD 151932 variability revisited (1987)

Vreux, Jean-Marie, Manfroid, Jean, Scuflaire, Richard, Magain, Pierre

The observation of variations in the blue absorption component of the He I lines as well as in the Si IV 4089 emission line of HD 151932 is reported. Possible explanations for these variations are...
