Landolt's natural GaAs u - b system is not very close to the standard U - B system and so it is likely that, because the transformations were made using a U - B colour term alone, systematic U - B differences exist for some kinds of stars namely, A-F stars, reddened B-A stars and giant A-F stars. ...

We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...
