X-ray, UV and optical analysis of supergiants: $\epsilon$ Ori

Raul E. Puebla, D. John Hillier, Janos Zsargó +2

We present a multi-wavelength (X-ray to optical) analysis, based on non-local thermodynamic equilibrium photospheric+wind models, of the B0 Ia-supergiant: $\epsilon$~Ori. The aim is to te…
