HD 184787

Spectral Classification of Stars in A Supplement to the Bright Star Catalogue MK spectral types are given for about 584 stars in A Supplement to theBright Star Catalogue. These are compared with Hipparcos parallaxes tocheck the reliability of those classifications. The estimated errors are+/-1.2 subtypes, and 10% of the luminosity classes may be wrong.

Investigations of the light variation of twelve AP stars in ten spectral regions Twelve Ap stars of known period and large amplitude were photometricallyinvestigated with the seven-color system based on glass filtersaccording to Straizys (1971) supplemented by three Schott filtercombinations in the red (total range 3400 to 7600 A). The light curvesfor each spectral range are presented, and some conclusions regardingthe importance of the data for possible model representations of theatmospheres of magnetic stars are set forth.
