Refined fundamental parameters of Canopus from combined near-IR interferometry and spectral energy distribution
Refined fundamental parameters of Canopus from combined near-IR interferometry and spectral energy distribution
Canopus, the brightest and closest yellow supergiant to our Solar System, offers a unique laboratory for understanding the physics of evolved massive stars. The accurate and precise PIONIER data allowed us to simultaneously measure the angular diameter and the limb darkening (LD) profile using different analytical laws. We found that …
