We present a spectroscopic analysis of the early-type massive binary system HD 93403. Using high resolution optical spectra, we clearly separate the primary and secondary components. For the first time, we are able to provide an orbital solution for both stars. Our new orbital parameters show discrepancies with the previous solution published by Thackeray & Emerson (1969). We further discuss several spectral features of HD 93403. We finally derive qualitative constraints on the inclination of…

Astrophysical parameters and multiplicity of massive stars: a mathematical approach
Often quoted for their crucial role in the ecology of galaxies, massive stars remain mysterious. The exact process leading to their formation, their stability or their stellar winds are so many
National Optical Astronomy Observatory
We use an X-ray stacking technique to investigate the evolution of the mean X-ray luminosity of ∼21,000 red galaxies at 0.3 ≤ z < 0.9 as a function of their stellar mass and redshift. The red
