Latitude-time distribution of the solar magnetic fields from 1975 to 2006
Minarovjech, M.
This paper presents the solar magnetic field distribution and meridional migration for the period of 1975-2006. A magnetic field latitude-time distribution map covering a 32-year period has been investigated. For this purpose a modified latitude-time diagram of the solar magnetic field distribution containing different kinds of fine structures is …
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.
