Abstract
We analyzed uvby and Hp light curves of 19 well-observed magnetic CP stars selected from the On-line Database of Photometric Observations of mCP Stars, of which light curves in all the five colours were similar. We assumed that among these stars with photometrically simple behaviour (PSB) could be found ones with a single photometric spot. The knowledge gained by analysing those simple situations would help us comprehend more complicated cases. Light curves of the 19 PSB mCP stars proved generally to be nearly symmetrical, but surprisingly diverse. The analysis shows that only in the case of HD 110956B, HD 188041, and perhaps HD 193722 are we able to explain their photometric behaviour by a simple one-spot model. Occurrence of more than one photometric spot on an mCP star is therefore more typical.
Abstract (in Czech)
Světelné křivky 19 fotometricky jednoduše proměnných mCP hvězd se ukazály být přibližně symetrické, ale překvapipivě odlišné. Analýza ukazuje, že pouze v případě HD 110956B, HD 188041 a snad HD 193722 jsme schopni jejich fotometrické chování vysvětlit jednoduchým jednoskvrnovým modelem. Výskyt více než jedné fotometrické skvrny na povrchu mCP hvězd je tak zcela typický.
