@article{Lyubimkov2010AccurateFP, title={Accurate fundamental parameters for A-, F- and G-type Supergiants in the solar neighbourhood}, author={L. Lyubimkov and D. Lambert and S. Rostopchin and T. M. Rachkovskaya and D. B. Poklad}, journal={Monthly Notices of the Royal Astronomical Society}, year={2010}, volume={402}, pages={1369-1379} }
The following parameters are determined for 63 Galactic supergiants in the solar neighbourhood: effective temperature T eff ; surface gravity log g; iron abundance log ∈(Fe); microturbulent parameter V t ; mass M/M ⊙ ; age t and distance d. A significant improvement in the accuracy of the determination of log g, and all parameters dependent on it, is obtained through application of van Leeuwen rereduction of the Hipparcos parallaxes. The typical error in the log g values is now ±0.06 dex for… CONTINUE READING
