Effective temperatures of magnetic CP stars: semi-fundamental data

Stępień, K.; Lipski, Ł.

A brief discussion of earlier determinations of effective temperatures of chemically peculiar stars is given. It is stressed that the effective temperature is a global parameter, important for stellar structure and evolution studies. It should, however, be used with caution in atmospheric investigations. New determinations of effective temperature…

Bolometric correction of the roAp star αCir

Brandão, I. M.; Cunha, M. S.; Gameiro, J. F.

For the first time, the bolometric correction of α Cir was determined. Two values, both based on an estimation of the total integrated flux, were obtained. For that purpose spectroscopic and photometric data of α Cir available in the literature was used. The values derived were then used to place α Cir in the HR diagram.
