Luminous Blue Variables (LBVs) are massive stars caught in a post-main sequence phase, during which they are losing a significant amount of mass. As, on one hand, it is thought tha…
Robust detection of CID double stars in SDSS
D. Pourbaix, G. R. Knapp, J. E. Gunn +5
Aims. The Sloan Digital Sky Survey (SDSS) offers a unique possibility of not only detecting Colour Induced Displacement (CID) double stars but also confirming these detections. Met…

Flavien Kiefer, Jean-Louis Halbwachs, Frédéric Arenou +9
In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the SOPHIE spectrograph at the Haute--Provence Observato…
Parallax and masses of alpha Centauri revisited
Dimitri Pourbaix, Henri M. J. Boffin
Context. Despite the thorough work of van Leeuwen (2007), the parallax of alpha Centauri is still far from being carved in stone. Any derivation of the individual masses is therefo…
